Twelve Tone App - Twelve Tone for iPad & Reviews

Enter a tone row by touching the staff or playing the piano keyboard.

You can create and work with sets and squares that have from 1 to 12 pitches.

Press the play button and hear your row played back to you as fast or as slow as you set.

Twelve Tone will automatically create the Prime, Inversion, Retrograde, and Retrograde Inversion Magic Square.

Mark pitches and rows in the square as you use them. The marks indicate the row form in which the pitch belonged; Prime, Inversion, Retrograde, and Retrograde Inversion.

Derive rows using Hexachords, Tetrachords or Trichords with the touch of a button. Color blocks help keep track of the different groups.

Twelve Tone lets you know if any notes are repeated by highlighting both notes, checking enharmonic values regardless of octave or accidentals.

Everything is saved between launches.

Lock the matrix to avoid accidentally marking or unmarking notes.

Erase the entire square with the touch of a button. (You will need to unlock the button first.)

Lock the prime row and transpose it to C to use the Absolute Pitch Method for row labeling in the matrix.

Two fun interfaces to work in; black ink on white, or chalk on a chalkboard.
