How to Tune the Viola

Making sure your instrument is well tuned is important for musicians of every level. For beginners especially, tuning helps engage the ear with the specific sound and frequency of the intended note. This engagement makes it easier to translate written music on the page into the right sound. More advanced violists are encouraged to teach themselves to tune by ear, where the violist listens for the perfect fifth interval between two strings when playing them together to tune. However it is still important to have a tuner on hand, especially when playing with others.

It is important to think of the process of tuning in itself as not just an act to get the instrument ready for playing, but to get your ears and mind in tune too. A good musician will use the process of tuning as a switch to move from everyday thinking into “practice mode.” If you are a beginner, you can do this too, by using the tuning process to really listen to your viola. When you tune, think about the sound, tune, timbre, and of course the pitch of the note itself as you change the note with the fine tuners.

The viola is tuned in perfect fifths - each string is tuned an interval of a perfect fifth from the string (or strings) next to it. The strings of the viola are tightened or loosened to produce the right note by the pegs and the fine tuners. Some violas only have fine tuners on the A string, whereas others have fine tuners on all 4 strings. If you buy a viola with only one fine tuner, you do have the option of getting the other three fine tuners installed into the tailpeice by a luthier. As their name suggests, the fine tuners are used for tuning the string if the string is off-pitch by a small interval of no more than half a tone or so. When the string is out of tune by half a tone or more, then the pegs are used to tune the note initially, with the fine tuner being used afterwards to make sure the note is exactly in tune. Beginners are usually advised not to tune with the pegs unless absolutely necessary, in order to avoid unnecessary string breakages. If you are beginning to tune from the peg, it is a good idea to tune with a scientific tuner to make sure you are not over-tightening the string, however with most low-end scientific tuners you will still have to be wary of attempting to tune an octave too high or too low. When you tune with the peg, only move the peg a few millimetres at a time - you will be surprised at how significantly such a small turn can affect the pitch of the string!

Tuning the Viola

When tuning any instrument, you should always tune from below the note, up. This prevents string breakages and systematizes the process of tuning, so you eventually become more familiar with the sound of a perfect, in-tune string. When tuning your viola, you should also always tune using the fine tuners when possible (if you have them - most learner violas should have fine tuners). When a fine tuner has been wound right down to the end of the screw, loosen the fine tuner all the way to the end of the screw before carefully tightening the tuning peg. This way, you prevent the string from being over-tightened.

When you are tuning your viola, play the note continuously with your bow and listen carefully to the string as it tightens towards the desired pitch. Remember: you may need to stop to tune halfway through a practice, especially if you are using new strings as they tend to stretch and may need tightening from the peg multiple times per practice session for the first few days.

It is advisable to start by tuning the A string first, followed by the D, G then C strings. When you start to become more familiar with the sound of the notes of the different strings, you can try tuning the strings against each other - this is known as relative tuning (see 'Relative Tuning' section).

Tuning using a Piano

how to tune the viola using a piano

Tuning your viola using a Piano or Keyboard is a relatively simple task. The picture below shows the piano keys that correspond with the strings on the violin. Make sure you use the 'Middle C' on the picture as a reference point so you don't try to tune your viola an octave too low, or too high. Play the note on the piano and match the correct string to the note. Remember to use the fine tuners on your viola to tune if the string is out by less than half a tone. Use the pedals on the piano so the note you play is able to sound freely, and so that you can have both hands available to tune the viola.

Relative Tuning

Relative tuning is a method of tuning the viola to itself and is a skill that requires a lot of practice and time. In the beginning, some people find it easier to hear the true pitch of the note by closing their eyes and tilting their left ear towards the F holes. You can try this too while you tune your viola. If you have seen an orchestra play live, you may have seen the orchestra pass around the A. The A string is played by the concertmaster (lead violinist) to make sure all members and sections of the orchestra are tuned properly. As a violist, you use the A that is 'passed' to you to tune your other strings. To do this, you first make sure the A string is in tune with the concertmaster, then play the A and D strings together, listening for the perfect fifth interval to ring in tune. Then play the D and G strings together, followed finally by the G and C. In order to tune like this you must have a good knowledge or what the strings sound like, and what a perfect fifth sounds like too. Perfect fifths tend to sound very resonant, so you may be able to tune this way if you listen carefully to the ringing sound, or by looking at how the strings vibrate when you play them together. Start listening for these notes when you tune as a beginner as it is a great skill to be able to identify notes by ear!

Alternate Tunings for the Viola

Generally, alternate tunings for the viola are not commonly used by violists. This is because the further away the string is tuned from the intended pitch, the worse the string works. Normal viola strings will snap if they are tuned too high, and will become too slack to play if tuned much too low. Some orchestral pieces of music require the retuning of the viola for sound projection purposes. If a viola has a solo part in an orchestra, then the strings may be tuned a semitone higher in order to produce a louder sound (as strings with increased tension will sound louder).

There are some alternative tunings for the viola if the viola is used in different genres, such as country fiddle playing. Outside of a few dozen traditional pieces however, these alternative tunings are rarely used.

If you are a beginner, you should always start learning the viola with standard tuning as standardized tuning gives you a better feel for the instrument and is easier to learn as a benchmark.

Common Tuning Problems

Pegs that slip out of place - The most common problem when tuning is pegs that slip out of place. To fix this problem try unwinding the peg a round or two and then tighten the peg again, pressing the peg reasonably hard into the peg box while turning the peg. Hopefully the peg will stick, and your viola will stay in tune!

Wound Down Fine Tuners - If you have wound the fine tuners down to the nub and they cannot screw down any further, you can fix this by first winding the fine tuner back as far as it will go without falling out. Then, tighten the string at the peg, no more than a few millimetres at a time, until the pitch is just under the open note you need. Then you can continue to tune the string at the fine tuner. This method of resetting the fine tuners will prevent the string from breaking or wearing out due to excess tightening. If you find that you over-turn the peg and the string then sounds higher than it is supposed to, you can unwind the peg slightly to fix this as you will not be able to use the unwound fine tuner to tune downwards.

If you still have difficulty with slipping pegs or if you find that your fine tuners are hard to turn then have a look at our Violin Maintenance Guide to read about what you can do to fix these problems.

Quick-Reference Tuning Tips

Tuning a viola is easy if you follow these simple tips:

  • Top Tip: Remember to always tune from below the note to prevent strings from overstretching and breaking.

  • Use the fine tuners as much as possible to prevent string breakages. When they become wound down to the nub, loosen them right the way up, use the peg to tighten the string to just below the note, and use the fine tuners to tune the note up the rest of the way. Don't over tighten the string at the peg as you will not be able to tune down with the loose fine tuners.

  • Tune the A string first, followed by D, G then C strings. This is how orchestral violists tune their violas. Getting into a good tuning routine helps!

  • If you are using a tuner then try humming the right note from the tuner first, before you tune, so you your brain knows exactly what note you are looking for. If you can't reach the note with your voice, then just visualise humming it, this has much the same effect.
