Piano Pitch Check

Does your piano need a pitch raise?

Your piano tuner wants a quick check before the visit. This takes about 20 seconds.

When ready, tap the button below and allow microphone access. We'll ask you to play a note and hold it — no skill needed.

Advanced settings

Set the cents-off threshold your tuner uses for a pitch raise or lower. Pianos more than this much off will be flagged as needing pre-tuning correction.

Cents off from A=440. Default 25. A piano more than this far flat needs a pitch raise; more than this far sharp needs a pitch lower.
