As a small instrument, violins tend to go out of tune more frequently than larger instruments. Violins that are used regularly, especially those with new strings, will usually stay in tune well once the strings stretch out and “settle in.” Keeping your violin in a case when not in use, and keeping it away from extremes of temperature or humidity will help it maintain its pitch.Resource: lvlmusicacademy.com
How do you tune a sharp violin?
Start by using a piano, tuning fork, or a video like this to find the correct pitch for the string you are tuning. Then, pluck (strum gently with your finger) or bow the string (the A string on the violin) and compare it to the note that corresponds in the tuner. If the tuner indicates that the string is higher or lower than the correct pitch, loosen or tighten it to get it closer to the proper pitch.
While tuning, be careful not to turn the peg too quickly or too far, as this can cause the string to snap. Also, always remember the old saying “righty tighty, lefty loosey.”
Once you have a good tune on your A string, try to match up your D and G strings by playing them together and listening for the perfect fifth interval. If the strings aren’t in tune, tune them with the pegs, and use the fine tuners last if necessary. The pegs can change the pitch drastically, so it’s best to get your strings close with them first and then make tiny adjustments with the fine tuners.
