Violin tuning notes
Standard violin tuning, from lowest to highest, is G3, D4, A4, E5. The strings are tuned in perfect fifths.
| Target | Note | Frequency |
|---|---|---|
| 1 | G3 | 196.00 Hz |
| 2 | D4 | 293.66 Hz |
| 3 | A4 | 440.00 Hz |
| 4 | E5 | 659.26 Hz |
Targets are listed in preset order. Frequencies above use A4 = 440 Hz; changing Reference A4 adjusts the live tuner targets.
How to tune your violin
Bow a steady open string or pluck it gently. Begin with A, then check the other strings. Make small adjustments with the fine tuners; large peg changes can put too much tension on a string.
Can I tune my violin to an orchestra’s reference pitch?
Yes. Change Reference A4 from 440 Hz to your ensemble’s reference, such as 442 Hz. All four string targets adjust with that setting.
What do flat, sharp, and cents mean?
Flat means your pitch is below the target; sharp means it is above it. A cent is one hundredth of a semitone. Move toward 0 cents using small adjustments. For strings, tighten to raise pitch and loosen to lower it.
Can I change the reference pitch?
Reference A4 defaults to 440 Hz and accepts 400–480 Hz. Match your ensemble’s reference before tuning. The selected preset keeps its note names while its target frequencies adjust.
