Braille is currently the only means in regular production whereby this can be done.
Production requires knowledge of music and braille music encoding.
It is labour intensive and therefore expensive. Four of the major braille music libraries have formed a shared catalogue of braille music, now there is a need to join the digital files to the database so that they can be shared. To enable these libraries to make the most efficient use of the expertise available. To reduce costs and duplication of effort. To enable these libraries to contribute their productions to form a shared resource.
