Don, do you and your clients network through the disabled community as well, to see if there are practicing musicians among them who have explored adaptability also?
It's been communicated to me somehow or other that you know SO MUCH about what you are doing in this area of music and disability that the help you need is always pretty specific and limited. I have a hard time knowing how to help. I don't want to waste your time, or mine, going over ground already worked. But if there is a stone unturned I'd be glad to spend some time looking for it, see?
And some info in this vein might help other newer members who, like me, have only that part of the picture we see in whatever thread is up and running. Is there a set of links, or could they be made, Mudcat threads or otherwise, that would make the picture bigger?
