Parts of the Instrument & Accessories Flashcards
What are the sides of your cello called?
Ribs
The ribs are thin pieces of wood that connect the top and the back of the cello along their edges. They are supported by the blocks and the neck. The back supports the blocks, neck, ribs, and sound post. Most ribs are made from the same material as the back of the cello, usually either maple or poplar. To the eye, the most prominent feature of the ribs is the flame of the wood (striping). This is the result of the wood fibers having grown in an undulating pattern.
Note: The ribs are one of the most fragile parts of the instrument. Handle them with care.
Where are the pegs on your cello?
Pegs
The pegs support the ends of the strings, and are used to tune the cello strings if they are very out of tune. They move the pitch of the strings a relatively large distance (as opposed to the fine tuners which move a small distance). The pegs are usually made of a very hard wood called ebony, however they can be made of other materials such as rosewood or boxwood.
Note: Be very careful with the pegs. Even the slightest bump can cause the pegs to slip and make the cello go very out of tune. If your cello is already very out of tune, it is very important that you consult your teacher before attempting to tune with the pegs. This can be a very dangerous procedure for both you and the instrument (strings can easily break).
Where is the upper bout on your cello?
What do you call the top of the upper bout?
The top of the upper bout is called the shoulders.
Name the black wire in this picture of the cello.
Tailgut
The tailgut is connected to the tailpiece of the cello and supports the tension of the strings. It passes over the saddle and wraps around the endpin.

What are the circular dots on the sides of the frog called?
Pearl Eyes
The pearl eyes are circular pieces of pearl which are inlayed on the sides of the frog.
Where is the button on your cello?
Button
What is a mute?
Mute
A mute is a rubber device that funtions to muffle the vibrations of the bridge and makes the sound slightly softer in volume. They can be found most commonly on the strings behind the bridge. Mutes are used in all types of music, but are most often seen in orchestral music. When you see “con sordino” in your music, this means to apply your mute. When you see “senza sordino” in your music, it means to take your mute off.
Where is your rock stop, and for what is it used?
Rock Stop
Rock stops are used to keep the endpin of the cello from slipping or pucturing surfaces. Rock stops come in many varieties and can be made of many types of materials. I find the strap variety (pictured below) to be the most reliable, but each cellist has their own personal preference for rock stops.
Where is the bridge on your cello?
Bridge
The bridge is the piece of wood that supports the tremendous tension of the strings (roughly 80 lbs), and is typically made of maple. It is only held in place by the tension of the strings.
There are two types of cello bridges: French bridges have a darker more colorful tone and Belgian bridges have a brighter more projecting tone. Which type do you have on your cello?
Note: If the tension of the strings is loosened very much, the bridge will fall off. If for whatever reason your bridge moves even slightly out of its regular position, it is important that you ask your teacher or your luthier to move it back into position; do not attempt this yourself. This can be a very dangerous procedure for both you and the instrument (bridges can easily break).
Also bridges are fitted to each instrument; a bridge on one cello will not fit on any other cello unless a luthier cuts it again to fit.
Where is the button on the bow?
Button
The button is located at the end of the stick behind the frog. The button has a screw inside, and when it is turned the tension of the bow hair changes, making it either tighter or looser. Buttons are usually made of a metal such as silver and often partly contain material that matches the material used for the frog of the bow. They also often contain pearl.
Where is the sound post on your cello?
Sound Post
The sound post is a thin cylindrical piece of wood located on the inside of the cello near the treble foot of the bridge on the A string side. It supports the pressure of the strings and bridge on the top and it is supported by the back of the cello. The sound post is usually made of spruce. It is only held in place by pressure.
Note: If all string tension is removed (all the pegs slip), the sound post can potentially fall down. If your sound post has fallen, immediately loosen all strings completely, remove strings, bridge, tailpiece, and maybe endpin (if it is loose). Contact your local luthier and make an appointment for them to set up your cello.
This cello is missing which major part?
Back
The back supports the blocks, neck, ribs, and sound post. Most backs are made from two bookmatched pieces of maple or poplar. To the eye, the most prominent feature of the back is the flame of the wood (striping). This is the result of the wood fibers having grown in an undulating pattern.

What is the purpose of rosin, and what is it made of?
Rosin
Rosin is hardened tree sap which is applied to the bow hair to make it sticky. This stickiness creates more friction when the bow pulls the string and creates more sound.
Where is the frog on your bow?
Frog
The frog is the large piece that is connected to the stick of your bow. It is often made of a very hard wood called ebony, however it can also be made of other materials such as ivory, animal bone, or tortoise shell. The frog serves several functions: it is a place for your hand to grip, it supports the tension of the hair, and it balances the stick toward the side where your hand grips. On the bottom it supports one end of the hair, and on the top it has a screw eyelet which the button screw passes through. When the button is turned, the frog moves either toward the button and making the hair tighter or away from the button making the hair looser.
What do you call the metal device on the string?
Wolf Eliminator
A wolf eliminator is a device which suppresses the wolf tone on your cello. The wolf tone is produced by a flaw in the design of the instrument and creates an effect where a particular pitch does not resonate properly (it usually occurs between Csharp to Gsharp). This disturbance can make it difficult to play the wolf tone with a beautiful sound. Wolf eliminators are most commonly placed behind the bridge on one of the lower strings (G or C).
Where are the blocks on your cello?
Blocks
There are six blocks total: four blocks for each of the corners of the “C” bouts, one block under the neck, and one block above the endpin. They support main structural points on the cello. The blocks are usually made of either spruce or willow.
Name this part of the cello.
Fingerboard
The fingerboard travels under the strings, and serves as a support structure for your fingers when they pull the string down. The fingerboard is made of a very hard wood called ebony. As your fingers travel down the fingerboard, toward the bridge, the sounding pitch gets higher.
This cello is missing which major piece?
Top
The top supports the bridge which supports the strings. The top is supported by blocks, the neck, the ribs, and the sound post, and houses the saddle at the bottom and the bass bar on the inside of the cello. Tops are usually made of spruce because it is light in weight, yet longitudinally strong and laterally flexible. To the eye, the most prominent feature of a spruce top is the darker vertical graining or the annual growth rings of the tree.
Where is the tailgut on your cello?
Tailgut
The tailgut is connected to the tailpiece of the cello and supports the tension of the strings. It passes over the saddle and wraps around the endpin.
Where is the neck on your cello?
Neck
The neck of the cello is located below the pegs and scroll, and supports the fingerboard, the nut, and the tension of the strings in the pegs. The neck is usually made of maple.
What is this large piece that is connected to the stick of your bow called?
Frog
The frog is the large piece that is connected to the stick of your bow. It is often made of a very hard wood called ebony, however it can also be made of other materials such as ivory, animal bone, or tortoise shell.

The following parts of the cello often are made of what hard wood?
fingerboard, nut, saddle, pegs, tailpiece, base of endpin, purfling, frog, tip of bow, button of bow
Ebony
Name this part of the cello.
Tailpiece
The tailpiece supports the strings after they pass through the bridge and is connected to the tailgut. The tailpiece is held in place by the tension of the strings (if the strings are loosened, it will simply fall off). The tailpiece houses the fine tuners. Tailpieces are often made of a very hard wood called ebony however they can be made of many other types of materials such as rosewood, boxwood, aluminum, or plastic.
Name this part of the cello.
“F” Hole
The “F” holes are the places on the cello where sound is projected out of the instrument. Here is how sound travels: string vibrates, bridge vibrates, top vibrates, sound post vibrates, back vibrates, the entire inner chamber vibrates, sound leaves via the “F” hole.
What do you call the wooden length of the bow that stretches between the frog and the tip?
Stick
The stick of the bow is the wooden length of your bow which stretches between the frog and the tip. The stick of the bow is typically made of a dense Brazilian wood called pernambuco, however lower-quality bows can be made of other materials such as carbon fiber or fiberglass. The stick should have a natural downward curve. When the hair is tightened, the curve of the stick will gradually decrease.
Note: If after you tighten the hair the stick does not have any curve, your bow has probably been tightened too much.
Where is the purfling on your cello?
Purfling
The purfling is both decorative and serves a structural purpose. The edge of the top and back are lined with two very thin layers of a hard wood called ebony which serves to limit damage if the edges sustain an impact.
Where is the saddle on your cello?
Saddle
The saddle is located above the endpin near the bottom of the cello, and is made of a very hard wood called ebony. It supports the tailgut as it passes between the tailpiece and the endpin.
Where is the pearl slide on your bow?
Pearl Slide
The pearl slide is located on the bottom of the frog.
