2.2.5 Auto_beam_engraver

Generate beams based on measure characteristics and observed Stems. Uses baseMoment, beatStructure, beamExceptions, measureLength, and measurePosition to decide when to start and stop a beam. Overriding beaming is done through Stem_engraver properties stemLeftBeamCount and stemRightBeamCount.

Music types accepted: beam-forbid-event

Properties (read)

autoBeaming (boolean)

If set to true then beams are generated automatically. If set to false, auto-beaming is switched off as soon as the current beam (if any) is finished according to the auto-beaming rules.

baseMoment (positive moment with no grace part)

Smallest unit of time that will stand on its own as a subdivided section.

beamExceptions (list)

An alist of exceptions to autobeam rules that normally end on beats.

beamHalfMeasure (boolean)

Whether to allow a beam to begin halfway through the measure in triple time, which could look like 6/8.

beatStructure (list)

List of baseMoments that are combined to make beats.

subdivideBeams (boolean)

If set, beams of mulitple stems may be subdivided by omitting a number of beamlets, dependent on maxSubdivideInterval, between beats at mulitiples of minSubdivideInterval.
