Mandolin Tuner

Mandolin tuning notes

Standard mandolin tuning is G3, G3, D4, D4, A4, A4, E5, E5. Each course contains two strings tuned to the same pitch.

Targets are listed in preset order. Frequencies above use A4 = 440 Hz; changing Reference A4 adjusts the live tuner targets.

How to tune your mandolin

Mute one string in a pair while tuning the other, then swap. Once both match the target, play the pair together and listen for beating. Check all four courses after changing string tension.

Why are there two buttons for each mandolin note?

The preset lists all eight strings. Each pair shares a pitch, so either matching target button works while you tune one string at a time.

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.
