This section explains how to typeset vocal music, and make sure that the lyrics will be aligned with the notes of their melody. \musicglyph glyph-name (string). glyph-name is converted to a musical symbol; for example, \musicglyph #”l” selects the natural sign from the. If these automatic decisions are not satisfactory, beaming can be entered explicitly; see Manual beams. Beams must be entered manually if beams are to be.

Notation manual tables A. The properties of a beam are determined at the start of its construction and any additional beam-property changes that occur before the beam has been completed will not take effect until the nextnew beam starts.
Beams must be entered manually if beams are to be extended over rests. Setting automatic beam behavior. When automatic beaming is enabled, the placement of automatic beams is determined by three context properties: When multiple voices are used the Staff context must be specified if the beaming is to be applied to all voices in the staff:.
Note that baseMoment defaults to one over the denominator of the current time signature if not set explicitly.
Beaming patterns that differ from the automatic defaults can be created; see Setting automatic beam behavior. A quantity of type moment is created by the deference function ly: They specify the number of beams to draw on the left and right side, respectively, of the refeeence note.
For this, you specify the internal grouping of beats in a measure as a list of numbers in Scheme syntax before the time signature. When automatic beaming is enabled, the placement of automatic beams is determined by the context properties baseMomentbeatStructureand beamExceptions. The beams of consecutive 16th or shorter notes are, by default, not subdivided.
This behavior can be modified to subdivide the beams into sub-groups by setting the property subdivideBeams. Changing the default automatic beaming settings for a time signature is described in Time signature.
LilyPond Notation Reference: Beams
By default, baseMoment referrence one over the denominator of the time signature. While this may seem cumbersome, it means that the current beaming settings need not be known in order to specify a new beaming pattern. Direction and placementGrace notes.
Unbeamed grace notes are not put into normal note beams. About automatic language selection. Changes in automatic beaming settings for a time signature are described in Time signature.
This behavior is controlled by the context property beamHalfMeasurewhich has effect only in time signatures with 3 in the numerator:. 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 and last notes in the group.
Beam-ending rules specified in the Score context apply to all staves, but can be modified at both Staff and Voice levels:. This page is for LilyPond Grace note beams and normal note beams can occur simultaneously. Sometimes it may make sense for a lone note surrounded by rests to carry both a left- and right-pointing flat flag.
By default baseMoment is set to one over the denominator of the time signature. This behavior can be tuned through the auto-knee-gap property. A kneed beam is drawn if the gap is larger than the value of auto-knee-gap plus the width of the beam object which depends on the duration of the notes and the slope of the beam. Grouping is a scheme list indicating the grouping to be applied to the beam.
And for left-pointing nibs at the start of a run of beamed notes, set stemLeftBeamCount instead Example 3.
LilyPond — Notation Reference
In this example, the last f is printed with only one beam on the left side, i. Beam setting changes can be limited to specific contexts. The extent of the feathered beam must be indicated manually using [ and ]and the beam feathering is turned on by specifying a direction to the Beam property grow-direction.
The default beam settings for the time signature can also be changed, so that the desired beaming will always be used. Special autobeaming rules other than ending a beam on a beat are defined in the beamExceptions property. The spacing in the printed output represents the note durations only approximately, but the MIDI output is exact. When this is done, the value of beatStructure must be set to be compatible with the new value of baseMoment.
For right-pointing nibs at the end of a run of beamed notes, set stemRightBeamCount to a positive value.
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.
