Twelve Tone vs PhonoPaper

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. • 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, 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

PhonoPaper is a camera app for playing pictures with encoded sound (PhonoPaper-codes). With this app, you can also create your own codes: 10 seconds of sound can be recorded from a microphone and converted into an image. [ Key features ] * PhonoPaper does not require access to the network for decoding; * PhonoPaper code is analogue, so it is not so sensitive to different types of the image distortion (bad camera, dark picture, wrinkled paper, etc.); at least you will hear the "silhouette" of the original sound; * code can be played in real-time with hand-controlled speed and direction; * code can be drawn by hand to get some unusual sounds. [ Examples of usage ] * voice messages (or pieces of music) on t-shirts, billboards, posters, postcards, goods; * audio labels for phonorecords; * audio examples in books; * secret messages; * art-experiments. [ How to use ] Launch the app, point the camera at the code (tap on the screen to focus if necessary) and smoothly scan the picture from left to right. The code should be parallel to the frame - try to keep the camera level. The black code markers (top and bottom) should fall entirely into the frame. If the application recognizes code markers, you will hear a sound. If you are unable to play the code smoothly, press the record button on the right side of the screen, this will enable automatic scanning.
