Viola tuning 101
Viola, as any other wood instrument, needs to be re-tuned from time to time. Weather, temperature and humidity affect the wood, causing it to contract and expand, which in turn changes the tension of the viola strings.
Viola is a four-string instrument, its strings are tuned with perfect fifth intervals between them. Starting from the thickest string to the thinniest (that is, from lowest to higher notes):
- String 1 – A4, the highest (thinniest) string
- String 2 – D4
- String 3 – G3
- String 4 – C3, the lowest (thickest) string
Tuning is achieved with two mechanisms: the four tuning pegs on the scroll for the approximate initial tuning and fine tuners on the tailpiece for finer adjustments. Some violas have just one fine tuner for E string, some have 2 for E and A strings, others have fine tuners for each string.
Familiarize yourself with the instrument to make sure you know where the tuning pegs and fine tuners are. To help you with that, you can check out illustrations on this WikiHow article on how to tune a violin (the process for viola is the same).
If your viola is only slightly out-of-tune, using fine tuners alone may be enough. But if the instrument is completely off-pitch, you'll need to start with adjusting the pegs, and use the fine tuners at the end to finish the tuning.
Always start tuning with the lowest string (G3) and then proceed to the higher ones: D4, A4 and finally E5.
Please refer to our instructions for tuning cello – the process of tuning a viola is mostly the same, for the instruments have much in common.
