There are several computer options that can be used by musicians who are blind to notate, read, and record music. Examples are provided in the following paragraphs; however, mention of a product does not imply endorsement.
Musicians who are blind can use a program called Sibelius Speaking  in combination with JAWS  screenreader and the Sibelius  music program to notate music. Sibelius Speaking is a script that allows JAWS to interface with the Sibelius music notation program.
A musician who is blind can use a Braille music translator program like Goodfeel  to transcribe music from Sibelius or other music notation programs into Braille.
To record audio and Musical Instrument Digital Interface (MIDI)  files, a person who is blind can use JAWS screenreader with Caketalking  scripts to use the multi-track digital audio workstation Sonar.  With these programs a musician who is blind can edit MIDI files, add effects to them, and create the final output to make an audio CD.
