Recently there was a post on the music stack by someone who had written a tune on a guitar using a tuning of his own invention. I would have liked to comment that Elizabeth Cotten wrote music on a guitar tuned backwards and that Worrell's "Spanish Fandango" is the reason the tuning he used is called "Spanish tuning." Although I had enough reputation to comment on other stacks, I had zip at the music stack.
I think it might be a good idea to have an award of the ability to comment on one stack of the recipient's choice for which he had little or no reputation. What do others think?
