Chaining and Back-Chaining

Whenever I hear the “Concerto for Trumpet in Eb” by Johann Nepomuk Hummel I have this flashback: I’m once again in high school, about to perform the Concerto (on a Bb trumpet). It’s an ambitious piece for any trumpet player, let alone a high schooler; let alone a kid from rural Alaska who has had no lessons. I’m nervous, of course, but I’ve practiced (or so I think), I’ve worked with my excellent accompanist a few times. I’ve never performed it before but I don’t give this much thought because I’m too nervous. I sit in the warm-up room and practice a little before I go perform. That’s not true. I practice a LOT. It’s becoming frighteningly clear to me–much too late–that I don’t really know this piece. I work the sections that are difficult (there are a lot) and begin to get tired. My chops are getting tender. I stop practicing and go perform with a feeling of trepidation in my gut.
