An extensive music composition and analysis tool. An indispensable resource for any musician or music teacher interested in dodecaphonic and set theory analysis.
• Enter a tone row by touching the staff or playing the piano keyboard (on iPad).
• It lets you know if any notes are repeated by highlighting both notes, checking enharmonic values regardless of octave or accidentals.
• Automatically creates the Prime, Inversion, Retrograde, and Retrograde Inversion Magic Square.
• Constantly updates the Interval Vectors and Circular Analysis of the tone row as you edit it.
• 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.
• Share a pdf of the notation, piano keyboard (iPad only), and circular analysis.
• Watch and listen to your row played with a selected rhythm pattern.
• Playback:
- Prime
- Prime then Retrograde
- Retrograde then Prime
- Retrograde
- Inversion
- Inversion then Retrograde Inversion
- Retrograde Inversion then Inversion
- Retrograde Inversion
• Each can be repeated and transposed with each iteration.
• The Root is kept within an octave above and below the original pitch when looping and transposing.
• 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
