12-note chromatic scale on AA, A♯, B, C, C♯, D, D♯, E, F, F♯, G, G♯.

Press to hear the scale played ascending.

All twelve semitones — every pitch in the octave. Not a key so much as the raw material every other scale selects from.

The notes

Each degree links to its pitch page. Note names use sharp spelling throughout — every accidental is written as a sharp (C♯, not D♭), the same convention as the note pages.

The step formula is 1–1–1–1–1–1–1–1–1–1–1–1 semitones — 12 steps that sum to a full octave (12 semitones) and return to A.
