An extensive music composition tool. Enter a tone row by touching the staff or playing the piano keyboard (on iPad). 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. Save your rows (rows may contain from 1 to 12 notes), complete with name and current P, R, I, RI matrix markings. Saved rows appear in a list with their name and midi numbers to help you identify them. Hear your row played at your set tempo with selected rhythmic pattern. Select from over a dozen rhythmic values / patterns. Watch the notes and piano keys highlight as the row is played. Select what form(s) of the row you want played just once or looped.- Prime- Prime then Retrograde- Retrograde then Prime- Retrograde- Inversion- Inversion then Retrograde Inversion- Retrograde Inversion then Inversion- Retrograde Inversion Each sequence can be repeated and transposed over a five (three on the iPhone) octave range, with none, one, two, or three beats separating repeated group of octaves. Select the direction you want the octaves played in.You can change any of these parameters on the fly. The rhythmic pattern changes at the beginning of the next loop. Twelve Tone will automatically create the Prime, Inversion, Retrograde, and Retrograde Inversion Magic Square. Matrix Audio! Hear the pitches as you mark them in the matrix square. The marks indicate the row form in which the pitch belonged; Prime, Inversion, Retrograde, and Retrograde Inversion. Lock the prime row and transpose it to C to use the Absolute Pitch Method for row labeling in the matrix.Comes preloaded with the following rows: Alban Berg's Lyric Suite Babbitt's Composition for Four Instruments Schoenberg's Variations for Orchestra Op.31 Schoenberg's Piano Piece Op.33a Webern's Concerto Op.24 Webern's Piano Variations Op.27 Webern's String Quartet Op.28
