Breath marks are entered using \breathe
:
c'4 \breathe d4
The glyph of the breath mark can be tweaked by overriding the
text
property of the BreathingSign
layout object with
any markup text. For example,
c'4 \property Voice.BreathingSign \override #'text = #(make-musicglyph-markup "scripts-rvarcomma") \breathe d4
