The Sound of Silence Duet

Thanks for this info, Ralph, and the very prompt reply.
What you have written is of great interest to me as an intermediate jazz player of sax and bass.
However, I am having trouble trying to open your scores. Which program do you use to create your music files? My computer doesn't recognize it.
I don't know whether it is me doing something daft or my computer system. My machine which is less than 12 months old, is working quite successfully at driving me mad!
Thanks again for your input.
