About automatic language selection. While this may seem cumbersome, it means that the current beaming settings need not be known in order to specify a new beaming pattern.
If a polyphonic voice ends while an automatic beam is still accepting notes, it is not typeset. Feathered beams are used to indicate that a small group of notes should be played at an increasing or decreasing tempo, without changing the overall referemce of the piece.
LilyPond — Notation Reference
Such beams can be specified manually by marking the begin and end point with [ and ]. Sometimes it may make sense for a lone note surrounded by rests to carry both a left- and right-pointing flat flag. If the placement of the notes and the sound in the MIDI output is to reflect the ritardando or accelerando indicated by the feathered beam the notes must be grouped as a music expression delimited by braces and preceded by a featherDurations command which specifies the ratio between the durations of the first referenc last notes in the group.
The beamExceptions rule can override the beatStructure setting if beamExceptions is not reset. Changes in automatic beaming settings for a time signature are described in Time signature. That is, the three or more beams stretch unbroken over entire groups of notes.

This behavior can be changed as shown:. When automatic beaming is enabled, the placement of automatic beams is determined by three context properties: If a beamExceptions rule is defined for the time signature in force, that rule alone is used to determine the beam placement; the values of baseMoment and beatStructure are ignored. Beamlets can be set to point in the direction of the beat to which they belong. A beamExceptions value must be complete exceptions list.
When the time signature is changed, default values of Timing. Note that baseMoment defaults to one over the denominator of the current time signature if not set explicitly.
The default values of these variables may be overridden as described below, or alternatively the default values themselves may be changed as explained in Time signature. Beaming-rules is a scheme alist or list of pairs that indicates the beam type and the grouping to be applied to beams containing notes with a shortest duration of that beam type. When multiple voices are used the Staff context must be specified if the beaming is to be applied to all voices in the staff:.
The spacing in the printed output represents the note durations only approximately, but the MIDI output is exact.

The beams of consecutive 16th or shorter notes are, by default, not subdivided. When set, multiple beams will be subdivided at intervals defined by the current value of baseMoment by reducing the multiple beams to just one beam between the sub-groups. By default, beamExceptions rules are defined for most common time signatures, so the beamExceptions rules must be disabled if automatic beaming is to be based on baseMoment and beatStructure. Grace note beams and normal note beams can occur simultaneously.
Do this with paired  beam indicators alone Eeference 4. Setting automatic beam behavior. The beamExceptions rules are disabled by. Beat grouping within a measure is controlled by the context property beatStructure.
This means that setting the time signature in one staff will affect the beaming of the other staves as well. Even more strict manual control with the beams reverence be achieved by setting the properties stemLeftBeamCount and stemRightBeamCount.
The value of baseMoment can be adjusted to change the beaming behavior, if desired. The first beam avoids sticking out flags the default ; the second beam strictly follows the beat. Also, when baseMoment is changed, beatStructure should also be referrence to match the new baseMoment:.
By default, baseMoment is one over the denominator of the time signature.
