On the P-525, use MENU > Voice > Transpose; on the P-125 and P-121, hold METRONOME + RHYTHM and press a designated key; and on the P-155, use the dedicated TRANSPOSE button. Check your model number before following a shortcut, since the button sequences and available ranges are not universal.
Find your Yamaha model before changing transpose
Look for the model number on the instrument’s identification label, then match it to the instructions below. If your piano is not listed or its controls differ, use the manual for that exact model. Yamaha’s US manual library lists manuals for current P-series, Arius, and Clavinova models.

Transpose a Yamaha P-525
- Press MENU repeatedly until the Voice menu appears.
- Select Transpose and press the right-arrow button.
- Use the left or right button to choose the amount.
- Press EXIT to close the Transpose display.
The P-525 range is -12 to +12 semitones, with 0 as normal pitch. Press the left and right buttons simultaneously to reset the setting to 0. Yamaha’s P-525 Owner’s Manual gives the example that +5 makes a played C sound as F.
Transpose a Yamaha P-125 or P-121
- Hold METRONOME and RHYTHM simultaneously.
- While holding them, press the keyboard key for the desired shift.
The documented range is -6 to +6 semitones: F#2 through B2 select downward shifts, C3 restores normal pitch, and C#3 through F#3 select upward shifts. Consult the P-125/P-121 Owner’s Manual if you need the exact key-to-shift mapping.

Transpose a Yamaha P-155
- Hold TRANSPOSE.
- Press –/NO to move down or +/YES to move up.
- Read the amount on the display while holding TRANSPOSE.
The P-155 range is -12 to +12 semitones. A nonzero setting lights the TRANSPOSE indicator. After selecting an amount, pressing TRANSPOSE toggles the function on or off without clearing the selected amount. See the P-155 Owner’s Manual for its controls and display behavior.
How transpose works—and what it may not affect
Transpose shifts the pitch produced by the keyboard in semitone steps. It can let you use familiar fingering while sounding in a different key, which may help match a singer or another instrument. Yamaha describes that purpose in the P-525 manual.

On the P-525, the Voice-menu transpose setting applies to keyboard performance, not Song playback. The manual provides a separate Transpose parameter in the Song menu. It also says keyboard performance data is sent with transposed MIDI note numbers, but incoming MIDI note numbers from an external device or computer are not affected by this keyboard setting. These distinctions are specific to the P-525; check your own model’s manual for playback and MIDI behavior.
Why the pitch may not seem to change
- The amount is 0: Check the displayed value or selected key; 0 means normal pitch.
- The function is switched off: On the P-155, a selected nonzero amount can be toggled off with TRANSPOSE. Check the indicator and toggle it back on if needed.
- You are listening to playback: On the P-525, keyboard transposition and Song playback transposition are separate settings.
- The shortcut does not match your piano: Yamaha uses different controls across models. Confirm the model number and consult its manual rather than trying another model’s key combination.
Another model-specific example: CLP-110
The CLP-110 uses a different key combination: hold A-1 and C#0 while pressing one of the F#2–F#3 keys. Its documented range is six semitones down or up. The P-155 manual is not a source for this procedure; use the CLP-110 Owner’s Manual for its own instructions.
