I like that strategy. I think many readers appreciate a few details to help orient themselves. Regarding technical language, is one possible guide the musical equivalent of what you might hear from the commentators while watching the Olympics? (Maybe a little less?)

I really appreciate the first two (what to listen for and context) in any set of notes. Themes across the programme could also work nicely. Maybe some interpretation/hermeneutics if there’s something interesting to say?

I am now having regrets about taking you on the Dueck Extended Foot Tour of King's Cross. I hope it's a quick recovery.
