Today, thanks to James Bowden, we are filling a small gap in our knowledge about music and combining it with Braille in a wonderful way.
So far, we know how Braille music notation works in principle and that it is structured differently from music notation for sighted people.
What we don’t yet know, however, is what “normal” musical notation actually looks like.
James has clearly illustrated this in his contribution using Braille graphics.
