How to tune a guitar
- Press Start Tuning and allow microphone access when your browser asks.
- Play one note. Pluck a single string or play one key, close to the microphone, and let it ring.
- Read the display. The big letter is the nearest note. The bar shows how far off you are: left is flat (tune up), right is sharp (tune down).
- Turn until it goes green. Inside your tolerance (±3 cents by default) the display turns green and the string gets a check mark.
Tips
- Always tune up to the note. If you overshoot, drop below the note and come back up so the string settles against the peg.
- New strings stretch for a day or two. Pull each string gently away from the fretboard and retune until it holds.
- Pluck with the same strength you play with. A very hard attack reads sharp for the first moment.
- Electric guitars: switch to the neck pickup and roll the tone knob down for the steadiest reading.
