David, Braille music has alterations and all elements needed do indicate what is to be played, as well as specific repetition devices to avoid having to read again a fragment that was present before. There’s also a clef indication, to simplify communication with sighted musicians. It is optional, since all notes are indicated with absolute octave, i.e. the current absolute octave holds until another one is specified. The lyrics and such textual contents are transcribed using grade 2, i.e. contracted cells sequences. The contents is thus to be interpreted in the context a a natural language if they are present in the score. And all this with only 64 6-dots cells. Readers of braille music are to be admired in my opinion… Here is example 6.1-1 taken from BANA 2015, which is the most recent reference for braille music (http://brailleauthority.org/music/Music_Braille_Code_2015.pdf). As mentionned previously in this thread, there may be differences in braille music as used in other countries, apart from text contents: |
And to be complete, I attach the MusicXML file for this small score, together with the result of translating it to ASCII braille for embossing and reading on a braille display, and to Unicode UTF-8. |
