Engraving tremolos with floating beams
If a tremolo’s total duration is less than a quarter-note, or exactly a
half-note, or between a half-note and a whole-note, it is normally
typeset with all beams touching the stems. Certain engraving styles
typeset some of these beams as centered floating beams that do not
touch the stems. The number of floating beams in this type of tremolo
is controlled with the 'gap-count
property of the Beam
object, and the size of the gaps between beams and stems is set with
the 'gap
property.
