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.
Row laboratory
Generate, hear, and analyze a twelve-tone row using prime, inversion, retrograde, and retrograde inversion forms.
A twelve-tone row presents all 12 pitch classes without repetition. It avoids tonal hierarchy and forms the basis for serial composition.
Prime
P₀The original ordered row.
Inversion
I₀Intervals are mirrored around the first pitch.
Retrograde
R₀The row played backward.
Retrograde inversion
RI₀The inversion played backward.
Twelve-tone matrix
All transpositions of the row and its inversion.
