[MusicTlk] Questions About Accessible Music Textbooks

[Dana Mohsen]

Hello all,
My name is Dana Ibrahim, and I am a blind musician studying piano and music composition.
I have a question regarding accessible music textbooks.
Note: by music textbooks I mean textbooks about music (harmony, counterpoint, analysis, etc) and not music scores.
Is there a digital music textbook that uses a combination of electronic braille and audio?
For instance, would there be a music textbook that contains a folder with both audio and braille options for the music textbook?
E.G. if I were to download a digital copy of a music textbook, would there be an option for it to come with audio, text documents and braille? I know that this sounds a bit complicated.
Thank you in advance.
Best regards,
Dana Ibrahim
