Parts of the Viola

Knowing the names of the different parts of the viola is essential for any beginner, so that the player has a clear understanding of what parts they may need to interact with in order to retune, restring and look after their instrument.

Parts of the Viola

Scroll

The scroll of the viola is the very top of the instrument above the pegbox. The scroll can be identified by its characteristic curl design; however some older instruments have scrolls that were more elaborately carved with animals or figures.

Tuning Pegs/Pegbox

The tuning pegs and pegbox are located at the top of the instrument under the scroll. This is where the strings are attached at the top. The end of the string is inserted into a small hole in the peg, which holds the string in place while it is wound around the peg to tighten the string. The majority of the tuning of the viola is performed by tightening the peg, with fine tuners sometimes being used (if fine tuners are fitted) for strings that are out of tune by less than half a tone.

Nut

The nut is the connector between the peg box and the fingerboard. The nut has four grooves in it which the strings sit in so that they are evenly spaced down the fingerboard. If you restring a viola or the strings are very loose, then you should check that the strings are sitting in the grooves at the nut and at the bridge before you start to tighten the strings.

Strings

The strings on the viola are tuned C,G,D,A from lowest to highest. Strings differ significantly in quality, and the quality of the strings makes a considerable difference to the tonal quality produced by the viola. Strings are made from a variety of different metals (mainly aluminium, steel and sometimes gold). However, some synthetic materials are also used to produce strings and 'cat gut’ strings made out of animal intestine are still relatively popular today.

Neck

The neck of the instrument is the part of the viola that carries most of the stress of the strings. It is the long wooden piece behind the fingerboard, which the fingerboard is glued to.

Fingerboard

The fingerboard is the smooth black playing surface glued to the neck of the viola underneath the strings. Violists sometimes get black residue on their fingers on the left-hand due to the black polish rubbing off. Eventually the fingerboard would need refinishing if this starts to happen as the colouring on the fingerboard will start to fade away.

Body

The body of the viola is the part that amplifies the sound in acoustic viola. The body of the viola can be made of a variety of different woods. While most violas have two-piece backs that are joined together with a seam down the middle, one-piece backs are preferred due to their increased resonance. The size of the body of the viola has been experimented with significantly over its history, in order to try and improve the resonance of the lower range of the viola.

Sound Post

The sound post is the round post inside the viola that runs from the front-piece to the back-piece under the bridge of the viola. The sounding post plays a key role in how the viola produces sound, and it also helps to support the structure of the viola from the pressure created by the tension of the strings.

F Holes

After the vibration from the string reverberates within the body of the viola, the sound waves are directed out of the body through the F holes. A good tip for beginners is to direct the F holes towards your audience. Doing this will allow the audience to experience the best sound possible. Of course, you do not need to worry about this if you play an electric viola, or if you are playing with a pick-up.

Bridge

The bridge of the viola comes in varying angles of curvature. A smaller angle makes it easier to play double or triple stops (playing two or three strings at the same time.) Whereas more curved bridges make it easier to hit the right notes without scraping across a wrong string. The bridge also has ridges on it that help to space the strings out evenly.

Fine Tuners

Fine tuners can be found either on all four strings, or just the A string. If you are a beginner, it is best to choose a viola with four fine tuners as it makes it significantly less likely that you will break a string while tuning. Fine tuners are essentially a screw that presses down a lever that then tightens the string fractionally. When a fine tuner reaches the end of the screw, it should be unscrewed completely and then the peg should be tightened before again using the fine tuner as this prevents over tightening the string.

Tailpiece/Endpin

The tailpiece is what the strings are attached to at the bottom of the instrument, closest to the players chin. The tailpiece is attached to the bottom of the instrument by the endpin or end button, a small button on the side of the viola that rubs against the player’s neck.

Chin Rest

The chin rest is an additional part added to the viola later in the viola’s history that supports the players chin when they are playing the instrument. The chin rest is important because it helps the player to hold the viola, which means that the left hand can then move freely up and down the fingerboard as required.

Parts of the Bow

Hair

The hair of the bow is the part that touches the string when playing. Usually the hair is made out of either a synthetic material or horse hair, and these strands need to be well-rosined to produce sound. If your bow is not well rosined, you may find that it slips on the string and produces a softer, whisper-like tone.

Frog

The frog is the part of the bow that the violiaist holds. The frog is where all the mechanics of the bow happen.

Screw

The screw is on the end of the frog which tightens and loosens the hair. If the screw on the end of the frog is completely unscrewed then the frog comes off the bow (it is easy to reattach) when the screw is tightened it stretches the hair of the bow closer to the end of the bow, thus tightening the tension of the hairs.

Stick

The main stick of the bow is usually made of wood, sometimes with a metal core. The stick needs to be supple and bendy to be able to support the tightening and loosening of the bow hair. A good bow should be light, and have a balance point (the point where you can balance the bow on one finger) around a quarter of the way up the bow from the frog. The balance point is important as it allows the violaist to perform advanced technical movements like spiccato (where the bow bounces off the string between each note).

Pad

The pad of the bow assists the player in holding the bow.
