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.
