Twelve Tone

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 Webern's Piano Variations Op.27 Webern's String Quartet Op.28
