I'm always happy to do something simpler, but I admit that I'm a bit at a loss as to how to convert the linked snippet to the construct you described. The snippet stores the \path for the clef in a variable ("my-clef") and then sets is at the stencil for the bass clef using a layout block like this: \layout { \context { \Score \override Clef.stencil = #(lambda (grob) (let* ((sz (ly:grob-property grob 'font-size 0)) (mlt (magstep sz)) (glyph (ly:grob-property grob 'glyph-name))) (cond ((equal? glyph "clefs.F") (ly:stencil-scale my-clef (* 1 mlt) (* 1 mlt))) ((equal? glyph "clefs.F_change") (ly:stencil-scale my-clef (* .8 mlt) (* .8 mlt))) (else (ly:clef::print grob))))) } } Where in that block would I indicate that kind of extra padding? Thanks, brin
