12-Tone Row Generator
Generate a random twelve-tone row and inspect Prime, Inversion, Retrograde, and Retrograde Inversion forms.
The 12-Tone Row Generator provides a simple workspace for creating a non-repeating chromatic row.
The page renders the prime form and the standard derived forms: inversion, retrograde, and retrograde inversion.
You can switch note spelling (sharps or flats), regenerate instantly, and copy the prime form as pitch classes.
This experience connects serial writing, motivic transformation, and fast pitch-class reading inside a compact tool.
