Unlike Braille Music (which is based on conventional music notation), Dodeka writes music with twelve notes on a staff of four lines. In the Dodeka configuration, there are no more flat or sharp signs and every note keeps its position within the staff regardless of the octave. The principle is simpler and means that one can quickly identify what note to play or sing by simply feeling where the note is positioned according to the four lines of the staff. (For more information about how the Dodeka alternative notation works, please visit the Dodeka music notation page)
On these touch-sensitive scores, a “ladder zone” is placed at the beginning of the notation to indicate the key, the tempo, and/ or where the piece begins.
The C line, which is thicker, enables the musician to find the lines indicating the position of the notes. Thanks to Dodeka innovative way to mark note duration, the length of the rectangles (that is the visual representation of the note) makes it possible to literally “feel” the length of the notes.
This graphical and sensory notation enables blind and partially sighted people to visualise music in their minds, read sheet music easily, as well as even compose their own pieces in an intuitive manner by only using their hands.
On top, since those sheet music use the exact same principle of the Dodeka notation, sighted people can also read those sheet visually, which makes them very useful in classroom or band with both visually impaired and sighted musicians. No need for other sheet music.
