Braille music is a Braille code that allows music to be notated using Braille cells so that music can be read by visually impaired musicians. The Braille music system was originally developed by Louis Braille.
Braille music uses the same six-position Braille cell as literary braille. However braille music assigns an entirely separate meaning to each braille symbol or group of symbols, different from literary braille, and has its own syntax and abbreviations.
Almost anything that can be written in standard print music notation can be written in braille music notation as well. However, braille music notation is a completely independent and well-developed notation system with its own conventions and syntax.
Visually impaired musicians can begin learning to read braille music about the time they have reasonable competence reading Grade 2 literary braille.
