Cello Exercise List

**This is a list that I have compiled from other teachers, and my own experience, hope you find this ever growing list useful**

KEY:
b= beginners
i= intermediate students
a= advanced students
fa= For all students

Body/Cello Position

Cello-Hug, b
• How to approach, tell the students to wrap their arms around their cello as if to give the instrument a hug. Although the teacher must emphasize for the student not to squeeze the cello but just give a relaxed hug.
• What to listen/watch for, the student must be made aware of the position, and level of comfort that comes with the hug. The student shoulders should not be raised or tense and the instrument should have correct contact with the body.
• Objective of exercise, the purpose of this exercise is make the student aware of the correct body position, without having to constantly remind them verbally of mistakes. Cello-Hug is an exercise that they (students) can take home with them and practice achieving that level of comfort until it becomes second nature.

Tri-pod, b
• How to approach, the teacher brings in a tripod and demonstrates the stability of the three legged apparatus. The teacher can demonstrate when only two of the legs are equal distance, and the other is not and how this can upset the balance and stability of the tripod. Once the point is made the teacher demonstrates how the feet/legs and the endpin make up a tripod and how that balance transfers into the stability in playing the cello
• What to listen/watch for, the students must understand what it feels like to not have the balance of the tripod position in order to accept it. The teacher must make the student aware of their position whenever they (student) are at the cello.
• Objective of exercise, to make the student aware of the role that their feet/legs play in the balance of their instrument. Also to make them aware of what feels like to be balanced.

Cleaning the Air Corridors, b
• How to approach, the student places the middle of their bow on the A-string, then on the C-string. The teacher demonstrates that nothing should be obstructing the path of the bow.
• What to listen/watch for, the student will say, if they have and obstruction (a knee or two) and the teacher will help the student “clear the air corridors” by adjusting to a new seating position, endpin height, or just fix a posture problem.
• Objective of exercise, to get the student use to playing without hitting one’s knees with the bow when playing. It also helps them understand to a greater depth the role of a good cello position.


Left Hand/Elbow

“Find the same note in different positions up to the end of the fingerboard”, I,a
• How to approach, the student can either play long held notes, short notes, or rhythms to engage this exercise. They begin at the lowest octave and can either find a note pattern, on the same string, different strings, or all of them (multiple octaves, sometimes the same octave but different strings).
• What to listen/watch for, intonation, ease of shifts, and clarity of rhythms.
• Objective of exercise, to make aware to the student the map that is in front of them, and will aid them in sight-reading, technique work in pieces, and overall understanding of where everything lies.

Scales, fa
• How to approach, scales can be tailored to meet each students technical needs and capabilities. A combination of bowing techniques and rhythms further intensify this exercise and make it a great work out for all.
• What to listen/watch for, intonation, clarity of shifts, positions, rhythms, and bow techniques. Also the student must be aware of key signatures and relative scales.
• Objective of exercise, to infuse in the curriculum elements of theory, intonation practice, and overall technique elements that a student will use for the rest of their lives.

skim the strings, fa
• How to approach, the teacher demonstrates the ease of sliding the the hand over the strings with out pressing or holding the strings down. The teacher can also “skim” into higher positions (thumb).
• What to listen/watch for, the teacher must make the student aware that the hand is not the first body part to move, but the elbow is.
• Objective of exercise, the most important aspect of this exercise is for the student to not be so focused on the hand motion, but the elbow motion. Once this is understood and absorbed the ease at which the student moves around on the instrument would have increased greatly.

Replacement exercise, I,a
• How to approach, the teacher demonstrates how one finger can play a note and then another finger can play that same note and continue on in either a pattern (1,2,3,4,3,2,1) or out of sequence. Tempo should be slow initially until it can be worked up to a suitable speed.
• What to listen/watch for, ease of elbow/hand movement, intonation, and stability.
• Objective of exercise, build a technical element by isolating it into its fundamentals. Once a desired tempo is reached the shift should not be audible to the teacher.

Trill Exercise, I,a
• How to approach, using rhythms the student takes the notes of the trill and executes them in an even steady rhythm, usually beginning at a slow tempo then speeding up the tempo to offer an extra challenge.
• What to listen/watch for, clear rhythms, steady tempo, intonation (the top trill not should be placed slightly higher than the in tune note). Also the student must make sure that the hand is as close to the finger board as possible, helping to facilitate the rapid movement of the fingers.
• Objective of exercise, to strengthen the individual fingers, and vary the speed that the student trills with.

Vibrato

Graduated rhythms, with gradually increasing speed (begin at ♪ = 58), i,a
• How to approach, student should practice this exercise with current scale (student should be secure with intonation of the selected scale) and focus on changing the pitch of each note with the rhythm of eighths, triplets, quadruplets, sextuplets, etc. with four beats in each measure (one note gets four beats).
• What to watch and listen for. Make sure that noticeable motion is originating from forearm, not fingers. Fingers however should be supple and very relaxed (down to the last joint). When at some of the lower speeds the “WA-AH” should be very pronounced, and so should the rhythms.
• Make sure that it is clear which of the two types is being focused on, or if both are being practiced alternately.

Sliding into the vibrato, fa
• How to approach, in one motion student begins roughly around first position (on second finger to begin with) and slides up the neck (roughly around fourth position) and as far back gradually decreasing the surface area of the slide until it settles on one note with vibrato.
• What to watch and listen for. Make sure the “ Wa- ah” sound is considerably stretched out and as the area decreases it becomes more of the sound of a vibrato. Motion should originate from the elbow, all other motion is simply an effect of that initial motion. Fingers should be supple, and and very loose and relaxed.
• Object of exercise is to understand, and remember the feeling of a relaxed hand. This is necessary for vibrato to take place.

Throwing the hand, fa (but best for -b)
• How to approach, the student throws the hand so that a feeling of shaking dice is felt. The student should be encouraged to try different rhythms, and actually continue the motion for an extend count (4/4). Teacher can even bring in a set of dice to help with the actual motion.
• What to listen/watch for, students (and teacher) should make sure that there is no tension, or visible muscle exertion occuring. The whole arm should feel relaxed all the way down to the hand, and it should feel as though the arm never tires (although a break should be taken after the fourth count). Teacher can also engage the student to place the right hand lightly on the left shoulder to also feel how the motion translates into the shoulder and back.
• Object of exercise is to have the student experience the relaxed motion of vibrato without the distraction of sound. The student then begins to understand how to perpetually keep the motion going and also learns where it originates.

Simulated Vibrato on the shoulder of the Cello, I, a
• How to approach, same as the “Throwing the hand” exercise except now the student has a fixed object to work against. The student should not just remain on one finger, but should go from finger to finger in any combination (but in a set meter).
• What to listen/watch for, the student should be aware of the flexibility of each finger, and also the approach the two types of vibrato (Lateral, Rotational)
• Object of exercise, the student gains more practice of the motion of the arm in vibrato, and also begins to engage the fingers against a fixed object without the distraction of sound. Flexibility of the fingers and types of vibrato should be discussed and the student should be able to demonstrate each before moving on to the strings. “Pass-off” can also be added.


The Pass-off, i,a
• How to approach, in a slow motion the teacher should demonstrate how (in vibrato) each finger passes off to the next using angle to connect each.
• What to listen/watch for, the student should begin slowly in order to hear the pitch change on the finger angle and also to be able to see an exaggerated finger angle pass off. Once the concept is understood the student should use different rhythms in a graduated fashion or set rhythms that continues from finger to finger. Scales can be used also to extend the exercise, and also build endurance.
• Object of exercise, to make the student aware of continuing the vibrato throughout a passage or scale. Rhythms, scales, and a metronome should be used extensively during this exercise.

Rhythm

March in place, while playing, fa
• How to approach, when the meter/rhythm of a particular section is cloudy the teacher instead of counting out the beats or telling the student the rhythm, the teacher suggests that the student keep time by either marching with the feet, or just lifting part of the feet in the given time.
• What to listen/watch for, the feet should be alternating in time and if the student should decide to just lift part of the foot it should be the front half, not the heel (simulating walking/marching). Make sure the student is following his/her own time, if not make them start over and stress the importance of them to be aware of the beat (feet).
• Object of exercise, to help the student internalize the beat/meter but doing it in by in which they realize the constraints of the rhythm/meter, and can learn how to play with it, and around it. Not to be used with a metronome.

March in place, and clap the rhythms, b,i
• How to approach, meant for beginners who are necessarily very coordinated to begin the exercise right before. The same idea is the same for each except instead of playing the notes while marching, the student is clapping out the rhythms. Can also add in saying the note names.
• What to Listen/Watch for, the teacher and student need to be aware that the feet never get off, and that they don't end up mimicing the rhythm that the hands are clapping, each should be independent. Once the student is secure with the feet and the hands, then saying the note names can be throwing into the mix.
• Object of Exercise, to help younger players build coordination of the body, and mind by having them do three things at a time which are all building on thing, sense of rhythm.

Count big beats out loud, fa
• How to approach, the student approaches a particular problematic passage by just counting out the big beats either while playing or not.
• What to listen/watch for, the student should be aware of where the big beats fall, if they are not then they must isolate the problem by either drawing lines through big beat notes, circling big beat notes, or the counting pattern above each note. (1 & 2& 3& 4&)
• Objective of exercise, the student should be aware of how each measure is divided up, into big and small beats. If they are not then this fundamental in rhythm and sight-reading must be covered until they can isolate big beats in any meter.

Bow/Rt. Hand/Rt. Arm

Bubbles, I,a
• How to approach, the student must understand the natural bounce that is built into the bow. Once this concept is grasped then the student can explore bouncing out of control and then trying to control it. As the control level is explored the exercise can then take place.
• What to listen/watch for, it is easy to just let the bow, and hand control the bounce (bubbles) but to effectively bring out the bubbles the student must employ the use of the elbow (as if drawing the bow) and a forward motion. Initially the student should isolate one spot in the bow (middle) to begin with, and once this is mastered they can then move to other point in the bow.
• Objective of exercise, in order for the “bubbles” to occur the student must relax the hand, arm, and fingers even. Mastery of the bubble exercise is translated into a more stable bow arm, control and variety in small strokes.

Getting in the String Exercise, fa
• How to approach, beginning on the –C string (because this string requires the most weight) have the student place the bow near the bridge (but not on it) and wiggle the string without making any sound. Once this is accomplished then have the student lessen the weight and draw a clear core tone from frog to tip.
• What to listen/watch for, When initially wiggling the string the students elbow should be pointed down, and the fingers should show the appearance of the weight that is being funneled through them. Once the student moves on to drawing the core tone the note should have a clear beginning (attack) and the sound/dynamic should not waiver throughout the bow. It should sound the same throughout and the elbow should make an arc-like motion with each down bow and up bow. Once –C string is understood the exercise should move to other strings to practice te different weight requirements for each.
• Objective of exercise, the student must learn to create a good core tone on each string and must learn how to effectively transfer weight from the arm to the hand to the bow. Also the student must learn the ease of drawing the bow by use of the elbow arc.

Spider, b
• How to approch, make sure students have a good grasp on where the fingers are placed on the bow. Once they do tell them they must inch their way up the stick without allowing gravity to help. Make it a game by recognizing the students who can crawl up the stick honestly.
• What to Listen/Watch for,make sure the students are holding their bow out in front of them, and crawling up the stick finger-by-finger simulating a spider.
• Object of exercise, to help the students build a firm but flexible grip, and to show how the fingers can have different tasks, but work together at the same time.

Finger Push-ups, b,i
• How to approach, while the bow is on the string the student does finger push-ups to check the cushion of flexibility in the right hand. Should be checked a different points in the bow.
• What to listen/watch for, make sure the students hand is not caving in under the weight of the arm, the fingers and entire hand should be very supple, and should not feel stuck or tense. The push-ups can be made into a game in which the teacher randomly calls out PUSH-UP as the student is drawing a bow. The student then learns that the hand must be supple and relaxed at all moments in the bow.
• Objective of exercise, the student is made aware of the need to all ways have a “shock” system in the right hand. This will not only build versatility in the right hand, but will also help relieve tension.

See-Saw, b,i
• How to approach, the student begins on two strings (-C and –G) and makes a see-saw like motion from string to string. This continues on each side-by-side string and then progresses into every other string and other combinations.
• What to listen/watch for, the teacher should make the student aware of the different angles on each string and how to find the angle in relation to the bridge. Once this aspect is absorbed the student should also note that the creator of the motion is the elbow and not the hand (esp. on large jumps). (but the hand motion can be explored at the teacher’s discretion)
• Objective of exercise, for the student to be made aware of the different angles on each string.

Scales, fa
• How to approach, scales can be tailored to meet each students technical needs and capabilities. A combination of bowing techniques and rhythms further intensify this exercise and make it a great work out for all.
• What to listen/watch for, intonation, clarity of shifts, positions, rhythms, and bow techniques. Also the student must be aware of key signatures and relative scales.
• Objective of exercise, to infuse in the curriculum elements of theory, intonation practice, and overall technique elements that a student will use for the rest of their lives.

Finger Placement

Replacement exercise, I,a
• How to approach, the teacher demonstrates how one finger can play a note and then another finger can play that same note and continue on in either a pattern (1,2,3,4,3,2,1) or out of sequence. Tempo should be slow initially until it can be worked up to a suitable speed.
• What to listen/watch for, ease of elbow/hand movement, intonation, and stability.
• Objective of exercise, build a technical element by isolating it into its fundamentals. Once a desired tempo is reached the shift should not be audible to the teacher.

Ghost Fingers/Miming, b
• How to approach, either a scale passage, or a particular moment in a piece is isolated and the motions of the different fingerings are gone through as though they are being played.
• What to listen/watch for, curved relaxed fingers, curved thumb that remains under the second finger, not pressing or caving in the wrist.
• Objective of exercise, to focus the student on the hand position and the notes while not letting them be distracted by sounds and the bowing.

Preparation and float, I,a
• How to approach, either isolate a particular two note passage, or pick tow notes a good distance away from each other. The idea is to keep the arm in motion once the shift begins until the final destination is reached. The finger shifting to, from, type of shift etc. should be made clear before the exercise is executed.
• What to listen/watch for, clear preparation note, light glissando that comes out of the string and a clear end note that evolves out of the gliss. The elbow, and arm motion are also a big factor in this exercise and should not be neglected. Intonation.
• Objective of exercise, To practice ease shifting from note to note.

Clam, b,i
• How to approach, away from the cello the student mimics the motion that a clam makes.
• What to listen/watch for, the student must not move the thumb excessively, and must not press with the fingers. Once the idea is made away from the cello then it can be applied but only making absolutely sure that the fingers don’t press and the thumb doesn’t cave in.
• Objective of exercise, to keep the student from squeezing the neck and allowing the thumb to cave in. Every finger (thumb included) should be rounded.

Dramatic Pinky placement, b
• How to approach, instead of the student placing their hand first finger first on the finger board, they approach it from the opposite way with the pinky.
• What to listen/watch for, the student should make a grand, dramatic gesture in order to get the point across. Make sure that once the hand is set the wrist does not cave in, but remains straight as if a continuations from the forearm.
• Objective of exercise, to make the student aware of how the wrist is to remain straight even with the hand on the finger board.
Relaxation

Stretching, fa
• How to approach, Before, during, and after playing the student learns to take time and stretch the muscles. The stretches can start as small as between each finger, and grow to be as large as bending over to touch one’s toes.
• What to listen/watch for, over doing it will lead to injury. The student must understand basic musculature in order to effectively stretch the correct muscles.
• Objective of exercise, to increase flexibility in the playing and decrease injury.

Playing slowly while taking note where you can relax, fa
• How to approach, either isolate a particular passage, or and entire movement where tension is a problem in. Once these areas are made clear go through slowly noting moments of tension and finding ways out of them by using the technique to help.
• What to listen/watch for, student must be aware that they are using the same motions, strokes, and gestures but at a much slower tempo.
• Objective of exercise, to help relieve even the most minute of tensions that might have found its way into the playing.

Meditation, fa
• How to approach, go to a quiet place, and either lay down or find yourself a comfortable position and focus on taking deep breaths and visualizing the performance, or just calm.
• What to listen/watch for, make sure the breaths are deep and steady and that you don’t allow yourself to fall asleep.
• Objective of exercise, to focus and calm the mind before a performance or a lesson.

Thumb Position

Block Fist, I
• How to approach, ask the student to make a fist (no need to squeeze though) and then place the fist (thumb first) on the string and rock from side to side and shift around (as if playing imaginary notes).
• What to listen/watch for, make sure the arm/wrist remains straight throught the course of the exercise. Also because the student is relatively new to the motion substantial breaks should be taken.
• Objective of exercise, to help prepare the student’s thumb (and elbow/arm) for the task of holding down notes in thumb position, and shifting.

Scales in place beginning on the harmonic, I
• How to approach, student places the thumb on the harmonic (seventh position if it were first finger) and plays a one octave scale.
• What to listen/watch for, the student should note that since the thumb is weak the strength will have to be built up by a lot of disciplined practice. The thumb should not cave in, and the fingers although in thumb position should remain curved. Proper elbow height and intonation should also be paid attention to.
• Objective of exercise, this exercise helps the student that is new to thumb position get some perspective on it before they jump fully into it. It is a painless way to practice thumb position for the hand and the arm.

Octaves/Intervals(misc. passages)

Bag-o-tricks, fa
• How to approach, on a problematic passage, or moment in a piece the issue is isolated and run through a battery of rhythms, retrograde motions, and loops.
• What to listen/watch for, student must be aware that they are practicing the correct bowings, and notes (with correct intonation) while the “Bag-o-tricks” are being instituted. If a mistake is made more than once the student can not move on to the next trick and must also go back to the previous trick to drill some more.
• Objective of exercise, to not only isolate the problem spot but to also drill it so many times in so many ways it actually becomes in grained in the hand and overrides any type of preconceived anxiety.

Gervais String Trio

Timmothy Baker, violin; Alvoy Bryan Jr., viola; Cora Phillips, cello








GROUP BIO

Formed in the winter of 2005 in Columbia, SC the Gervais String Trio takes its name from Gervais street which runs through downtown Columbia. While in graduate school the three members of the GST decided to focus their energies on building a chamber group that can perform at the highest level possible yet at the same time tackling teaching and community out-reach endeavors.

Investigating the Fundementals of Vibrato By Cora Phillips

Vibrato in the simplest term is the alteration of pitch at such a high velocity by the finger that it is not readily noticed as a pitch change but rather as an effect. Milly B. Stanfield states that, “Vibrato to a string player is like a colour to a painter and in its relation to musical interpretation it often requires as much thought and care as the blending of tints and hues in oils and water colours.” It should be noted that there are many, many avenues of approach to the art of vibrato and no single “way” can be touted as the only way.

In the exploration of the fundamental building blocks of varying the shades of vibrato three interconnected motions come into focus; Angle of the elbow, Angle of the fingers and Height of the fingers. In the aspect of the physics of vibrato; arm weight, speed of the arm and the relationship of the thumb to the rest of the unit (arm, hand) are the key points of examination. Later once all these points have been made and investigated the two types of vibrato (Lateral, and Rotational) will be defined and then related in general terms to the three interconnected motions, and the physics of vibrato

Vibrato is not just the movement of the fingers, it is actually on the big picture the combined direct movement of the forearm, upper arm muscles coming from the back and the hand. Vibrato must begin in a very relaxed place in the back, it cannot be forced or the desired effect won’t be captured and only tension will thrive. Allowing the connection between the back and the upper arm to relax permits the forearm to create motion. It is interesting to note that angle of the elbow can create different types of vibrato colors if those effects are so desired. Once the forearm is in motion the momentum is simply transferred through the hand. The forearm, wrist, and hand should always be viewed as one unit. Even in thumb position the mechanics of the vibrato should not change.

In the fingers the number one problem of most cellists is sustaining the vibrato from finger to finger i.e. note to note. It should be noted that the fingers are made up of four joints (including those of the knuckles too) and there is flexibility in these joints both forwards and backwards, left to right and even in the finger pads. The height and curvature of each finger also aid the process of leading the vibrato from note to note. Exercises that help build this concept are the “The Pass-off”, where in a slow motion the teacher should demonstrate how (in vibrato) each finger passes off to the next using angle to connect each. Another exercise that can be used to strengthen this technique is the “Graduated Rhythms” this should be practiced with a current scale (student should be secure with intonation of the selected scale) and focus on changing the pitch of each note with the rhythm of eighths, triplets, quadruplets, sextuplets, etc. with four beats in each measure (one note gets four beats). This exercise will help tie in the main element of finger angle in “Pass-off” along with rhythm studies and intonation work with scales. (for more exercises see the posting "Exercises")

In vibrato the role of the thumb is often overlooked. Most students either (in the beginning stages) remove the thumb from the neck claiming it hinders the motion, or use pressure to keep it from moving. In either case the results can hinder the growth of the vibrato, the freedom of the fingers and the intonation. The job of the thumb is pretty simple it is merely to add balance and stability to the hand throughout the motion. Further explanation of this can be explained by making a correlation between the relationships of the thumb, finger of motion, and the rest of the hand (arm) to that of a simple machine, to be specific a lever.

There are six simple machines, and their purpose is to facilitate force in order to maximize the outcome (work). The lever encompasses three main parts which are load, effort, and the pivot point. It is important to note before any further exploration into this comparison, that one must not confuse the element of vibrato with that of loads, forces, and work. This is simply an idea, a spark rather that can help solidify the role of the thumb in vibrato, and how it can also help in the process of varying speeds.

It is important to note that there are three classes of levers, however only the first two are of interest to this theory, First Class Levers (FCL), and Second Class Levers (SCL). In FCL the pivot point lies at the point between the Load and the Effort. Load can be defined as the object that is being moved and Effort is the energy that is being applied to move the Load.

EX.1

A connection can be shaped between the finger of motion and the Load (lets say the first finger), and the arm (encompassing the hand) with the Effort. In the FCL the pivot point is fixed (doesn’t change) but the thumb does vary its position slightly depending on the finger of motion. The point of a pivot point in the FCL is to facilitate balance between the Effort, and the Load which move in opposite direction of each other.

In FCL the placement of the pivot point between the two points (Load, Effort) can vary the force, speed, and distance. In vibrato there is no distance to be made but the weight, and speed are elements that are utilized and the point at which the thumb makes contact (and the finger under which it lies) have a direct connection to the speed, and the ability to sustain the motion. This is because once the arm is in motion and the weight is centered in the thumb a natural ricochet occurs. The finger of motion also helps to center the weight, but it is important to note that it is the thumb that centers the finger of motion.

SCL are created when the pivot point lies behind Load and the Effort. In vibrato this can be compared to the vibrato in thumb position, in which the thumb is still the anchor to the hand, but it is no longer under it.

EX.2


Another example is when exploring new ways of using the vibrato in lower positions it is possible to place the thumb behind the first finger to create a different color. In either case of the FCL, or the SCL the pivot point (thumb) is the source of stability of the machine (vibrato) and without it the natural sustaining power would be lost.

It is important to develop freedom and suppleness in the thumb. “…all cramping of the thumb must be avoided. If pressure of the latter on the neck of the instrument is as light as it should be, the movement of the forearm will communicate itself and produce the same periodical oscillation as that of the free fingers.” (Alexanian, Diran. Traite Theorique et Pratique du Violoncello. Paris: Edition Salabert, 1980)

Once a student has mastered the general motion of the arm, wrist, and hand moving as one unit they may begin to notice that in certain areas on the finger board and in certain phrases the vibrato may not seem to work as well, and they may have to modify it slightly to achieve the desired effect. It is at this point that an introduction into the two types of vibrato should be explored and practiced.

Lateral vibrato is a motion that benefits from the weight lying behind the finger of motion, and it is this forward moving weight that propels the fingers to move. Another aspect in Lateral vibrato is the motion of the arm. The arm (forearm) moves forward and only returns back to its starting place by momentum. It is this forward motion of the arm that compels the hand to move also but it is a delayed motion in relation to the forearm.

A connection can be drawn between the SCL discussed earlier, although the pivot point is not always behind the hand. On the smallest level the fingers in Lateral vibrato are utilizing the flexibility of the joints in the fingers between the Distal and Middle bones and the Middle and Proximal bones. It is this flexibility that is coupled with the forward moving arm that gives this particular vibrato its personality. The hand is actually moving sideways and it works best when in the restrictive area of the neck. Whenever the need calls it is possible to either speed up the vibrato gradually or slow it down (it is much easier to control speed with lateral vibrato). Some useful exercises are “Throwing the Hand”, in which the student throws the hand so that a feeling of shaking dice is felt. The student should be encouraged to try different rhythms, and actually continue the motion for an extend count (4/4). “Knocking on the Door”, the same idea as “Throwing the Hand” but using more force in the forearm. A good practice of the hand motion of Lateral vibrato would be trying it out on the shoulder of the cello on each finger in order to work up the muscle memory.

Rotational vibrato is when the general hand (arm) motion rotates like that of turning a door knob (often called the “door knob” vibrato). Instead of the forward motion like that of Lateral vibrato Rotational uses this right/left turning in the forearm to give it its sound. A connection can also made between Rotational vibrato and that of the FCL. The pivot point is typically centered between the finger of motion and the rest of the hand. Flexibility in the small joints of the fingers is not as crucial to Rotational vibrato as it to Lateral vibrato however the curved shape of the fingers and thumb is very important. The reasoning for this is the curved shape lends strength to the finger (like that of an arch) so that it won’t collapse under the weight of the arm (finger strength is also important here too).

It is important to note to students that Rotational vibrato is often best used for short bursts of vibrato, maybe on a note with accents, or on a held note in a quick tempo. The reasoning behind this is that the energy that is being used to initiate the motion has to be utilized in two directions, forward (sharp) and backwards (flat). In Lateral vibrato the motion is forward and the weight is centered behind the finger of motion there by giving it the sustaining force of the ricochet. In Rotational there is no natural ricochet so the energy expended forward, must also be expended backwards too.

Exercises that will help grasp the motion of Rotational vibrato are “The Door Knob” in which the forearm (wrist, and hand) twist from left to right as if twisting a door knob. This exercise can be used away from the cello, and also on the cello.
Generally when one sets out to teach vibrato they realize that they can’t just tell the student to shake their arm and expect the concept to be understood. Typically students (especially beginners) have already decided in their minds what vibrato is and it is at this point that the bad habits begin. In order to quell these bad habits teachers must be able to explain the motion in everyday terms, and draw correlations with activities that are generally understood for example like bouncing a ball. Once the student can relate the actions of everyday life back to the cello it will help ease the student into better vibrato awareness. Using the “Bouncing Imaginary Ball”, Door Knob”, “Throwing the Hand”, and “Pounding the Door” exercises builds from that knowledge of everyday actions and helps the pupil relate to the motion of vibrato.

Usually when a child begins wiggling their fingers, or develops a spontaneous spasm in their left arm they are trying to make their teacher aware that they know what vibrato is and they want to be able to do it. It is at this crucial moment that the teacher must select a path of explanation and a progressive curriculum so that the student is not left confused with a mass of information. With the motion exercises the teacher is conveying to the student the feel of vibrato, where the motion originates and how to sustain it. This should be the first phase and it should be a silent one either away from the cello or on the finger board. In phase one the teacher should ask the student to be aware of the parts of the arm that are moving and how the hand responds to this motion.

Phase two should begin with graduated rhythms at a set tempo with scales to really help track the progress. Students may find this level quite dull at times so in order to give them a periodic push in the lessons step up the tempo to a level where the rhythms are really difficult to do and the vibrato just happens naturally. This will give the student that boost of confidence and keep them going strong with the exercise. During phase two, the three interconnected vibrato motions should be discussed (angle of elbow, angle of fingers, and height of fingers) along with the two types of vibrato. It is important to stress the importance of making the pupil aware of these concepts rather than overwhelming them with too much knowledge. This can all be gauged by how quickly they (student) pick up the other concepts of vibrato.

Lastly in phase three, the student should be able to vary the speed, weight and develop the knowledge of how vibrato can be used to shape phrase, imply motion, and create neat effects. This last phase should be implemented in the current repertoire of the student. The teacher should stress the importance to the student that vibrato is not something you use all the time and in the same way. It is a texture that should be consciously used in an appropriate manner.

Christopher Bunting in his Essay on the Craft of ‘Cello-Playing writes, “…what vibrato should not be. It should not be an all-purpose varnish laid on thickly over a bad painting to conceal it defects.” It is in this manner that many are confused about the art of vibrato. It should be used only when necessary, when the music calls for it, and never the same way twice. It should not be a mechanical motion but should inspire freedom in the music making and the enhancement of the senses. With a clear and direct curriculum of study vibrato can be approached and understood by even the youngest players.
