Twelve Tone

A music composition / analysis tool. Create a tone row by clicking on the staff or the piano keyboard. Twelve Tone will automatically create the Prime, Inversion, Retrograde, and Retrograde Inversion Magic Square. Save your rows or pitch class sets of 1 to 12 tones, with its name, current P, R, I, RI matrix markings, derivation and preferred accidentals settings. Save and Share PDFs of the notation, magic square, circular diagram, and piano representation of the tone row or set. Twelve Tone lets you know if any notes are repeated by highlighting both notes. Press the play button and hear your set played back with your selected rhythm. Select what form(s) of the row you want played (once or looped); • Prime • Prime then Retrograde • Retrograde then Prime • Retrograde • Inversion • Inversion then Retrograde Inversion • Retrograde Inversion then Inversion • Retrograde Inversion Select the transposition interval and direction when looping playback. Hear the pitches as you mark them in the magic square. The marks indicate the row form in which the pitch belonged; Prime, Inversion, Retrograde, and Retrograde Inversion. Lock the square to avoid accidentally marking or unmarking notes, and erase the entire square with the touch of a button. Lock the prime row notation and transpose it to C to use the Absolute Pitch Method for labeling in the matrix.
