How to Tune a Violin
Tuning your violin is essential for producing beautiful music. The standard violin tuning is G-D-A-E (from the lowest string to the highest). The strings are tuned in perfect fifths, which is the interval that defines the violin family's characteristic sound.
Begin by tuning the A string to A4 (440 Hz), which is the standard concert pitch. Then tune the D string a perfect fifth below A, followed by the G string a perfect fifth below D, and finally the E string a perfect fifth above A. Fine tuners on the tailpiece allow for small adjustments, while the pegs are used for larger changes.
How to Use This Violin Tuner
- Select your tuning from the dropdown menu (Standard GDAE is selected by default).
- Click the microphone button and allow microphone access when prompted.
- Bow or pluck a single string on your violin. The tuner will automatically detect which string you're playing.
- You can also tap a specific string button to tune that string. The tuner will show how sharp or flat you are from the target note.
- Turn the fine tuner or peg until the indicator is centered and the status shows "In Tune."
- Repeat for each string until your violin is fully in tune.
Understanding Violin Tuning
Standard (GDAE) — The universal tuning for violin, with strings tuned in perfect fifths: G3, D4, A4, E5. This tuning is used in classical, jazz, folk, and virtually all other violin genres.
Open G (GDGB) — An open tuning that produces a G major chord when all strings are bowed open. Popular in folk and fiddle music, it simplifies playing in the key of G major.
Cross Tuning (AEAE) — Also known as high-bass tuning, this creates octave pairs perfect for old-time Appalachian fiddle music. The symmetrical intervals make certain drone patterns very natural and are a hallmark of the tradition.
