5 Breathing signs, also used for phrasing, do normally not influence
6 global spacing -- only if space gets tight, notes are shifted to make
7 room for the breathing sign. Breathing signs break beams running
8 through their voice. In the following example, the notes in the first
9 two measures all have the same distance from each other.
11 Breathing signs are available in different tastes: commas (default),
12 ticks, vees and `railroad tracks' (caesura).
14 Gregorian chant notation sometimes also uses commas and ticks, but in
15 smaller font size (we call it 'virgula' and 'caesura'). However, the
16 most common breathing signs are divisio minima/maior/maxima and
17 finalis, the latter three looking similar to bar glyphs.
