Questions and answers

What are the standard guitar notes?

From the thickest string to the thinnest: E2, A2, D3, G3, B3, E4 (E A D G B E). Tap a string below the tuner to hear its note.

Why does the tuner jump between notes?

Play one string at a time, let it ring and keep the others quiet. Noise in the room can confuse it; move the phone or laptop closer to the guitar.

Is my sound recorded?

No. The sound is analyzed on your device and never recorded or sent.
