I have now used this successfully in four scores (four parts of one work), but I have a mystery.
In the first three, it worked perfectly as expected. However, in the fourth (a larger score) it worked for a while and then the change clefs reverted to the original default size. I had to correct this my using an explicit font-size override when it went wrong, but this also lasted only a certain way and then needed to be repeated. I cannot think of anything in the score which would have any bearing on this, apart from one place (much later than where it went wrong) where I did a \once \override on the clef extent. It doesn't really matter because I've worked round it fine, but I am left wondering what made it go wrong as I can't think of a mechanism to cause it.

Something like this? \version "2.22.2" \layout { \context { \Score \override Clef.font-size = #(lambda (grob) (let* ((glyph (ly:grob-property grob 'glyph-name)) (is-change (string-endswith glyph "_change"))) (if is-change 0.5 ;; adjust 0))) \override Clef.before-line-breaking = #(lambda (grob) ;; Necessary to trigger font-size callback. Otherwise it is ;; not triggered because font-size is used via the same property ;; alist chain mechanism as markups. (ly:grob-property grob 'font-size)) } } { \clef "treble" c''1 \clef bass c1 } Best, Jean
