The D/deaf can gain just as much enjoyment from music as we can, they do it all by different feelings they gain from the vibrations. Have you ever been to a disco for the D/deaf, its wonderfully liberating to say the least. They have great rhythm. There are also some very famous Deaf musicians but I won't go into naming them.
I first became interested in signing when a young man placed his hand on my guitar when I was playing at a club, I was very offended at first then later felt very embarrassed when I realised he was profoundly Deaf, it was then I took up learning BSL (British Sign Language)
