Next tuning check: Dec 21, 2026

Yamaha recommends at least annual tuning for an established piano and twice during the first year; frequent use or unstable conditions justify an earlier professional check.

Read before relying

Context matters.

  • A technician should decide whether the piano needs pitch correction, regulation, voicing or repair; those are different services.
  • Large humidity swings, relocation and heavy use can shorten tuning stability even when the calendar interval has not elapsed.
  • Do not attempt high-tension piano tuning without appropriate training and tools.

Questions answered

What to know before using the result.

How often should an acoustic piano be tuned?

Yamaha recommends at least annual tuning for an established piano and two tunings during the first year; heavy use or unstable conditions may justify more.

Does moving a piano change the schedule?

A move or major humidity change can destabilize pitch, so the calculator promotes a professional check rather than waiting for the calendar date.

Are tuning, regulation and voicing the same service?

No. Tuning corrects pitch; regulation adjusts action and controls; voicing changes tonal balance. A technician determines what is needed.
