Piano Key Signature Chart
All 15 keys on the staff and the keyboard · see exactly which black keys you play · tap to hear
How to play
- The keyboard under the staff lights every note in the key, so you can see at a glance which black keys the signature makes you play (the amber key is the tonic). Tap a key to draw its signature and hear its scale. Switch Treble/Bass clef and Major/Minor — every signature is shared by a major key and its relative minor.
- Sharps are always added in the order F♯ C♯ G♯ D♯ A♯ E♯ B♯; flats in the reverse order B♭ E♭ A♭ D♭ G♭ C♭ F♭. Each accidental sits on a fixed line or space (shown correctly for both clefs).
- The scale notes appear as chips with their degree numbers — tap any note to hear it, or use Play scale / Play chord (the tonic triad).
- To name a sharp key: the last sharp is one step below the tonic. For flat keys, the second‑to‑last flat is the tonic. Three keys have enharmonic twins (B=C♭, F♯=G♭, C♯=D♭). Vol sets volume.
- Keyboard — Tab to any key, clef, mode, note or control, Enter/Space to activate.
