I fat-fingered the keyboard on my laptop and got this: flute-notes = { \override BreathingSigh.Y-offset = #2.6 %% also tried #5.0 and some really big numbers; no effect 7 bars of music in 4/4 }
AND I never got an error message. This seems to mean that Scheme has no checks for valid identifiers. I’m reminded of a program we had back in the early 1970’s; it printed an alphabetized list of all the identifiers in a BASIC program. If you’d misspelled something it jumped right out at you. Something like that would have saved me about two hours tonight. sigh (as it were)
