Richard, Jumping off from what’s above, I discovered your trill page. Wow. What a work! Thank you.
One question: Much music has a “+” above the staff that I’ve always thought to be a trill indication, yet you don’t mention that symbol in your exhaustive website. Have I got it wrong that it’s a trill, and (if it is a trill) is there a preferred way to play those?
Again, thank you. — k
