Comment #22 on issue 2717 by [email protected]: Patch: Implement \hidden/\hide as shorthands for \tweak/\override #'stencil = ##f
http://code.google.com/p/lilypond/issues/detail?id=2717
I find the term "\single" a bit confusing; < \only\hideNotes c e g > or < \just\hideNotes c e g > are possible alternatives, but I am not convinced of either one.
