Abstract

Aspects of automatic conversion between sheet music and Braille music are studied in this paper. The discussion is focused on syntactical structuring of information carried as sheet music and as Braille music (their digital representations). The structuring is founded on context-free methods. Syntactical structures of a given piece of music create so called lexicon. Syntactical structures are reflected in the space of sounds/notes. This dependency is a many-to-one mapping for sheet music and is a many-to-many relation in case of Braille music. The dependency between lexicon and the space of sounds/notes defines semantics of the given language. Both syntactic structuring and semantic valuation produce a basis for an automatic conversion between both languages: printed music notation and Braille music.
