Seems impossible? Luckily its not.
I know Braille but not at this level, with its specific notation and difficulty in sourcing materials let alone finding someone who knows it and can teach it .....
My colleagues recently hosted a Braille Music Workshop Day to great success.
With new technology coming on line all the time its great news when more and more things can be opened up and utilised in such a positive way.
Here's a great video about Braille Music from the Guardian. Fascinating.
