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.

Note that baseMoment defaults to one over the denominator of the current time signature if not set explicitly.
LilyPond Notation Reference: Beams
Direction and placementGrace notes. If no setting is included in a lower-level context, the setting of the enclosing context will apply. General input and output 3.
While this may seem cumbersome, it means that the current beaming settings need not be known in order to specify a new beaming pattern. That is, every exception that should be applied must be included in the setting.
And for left-pointing nibs at the start of a run of nltation notes, set stemLeftBeamCount instead Example 3. The properties of a beam notatiln 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. By default, the Timing translator is aliased to the Score context. The beams of consecutive 16th or shorter notes are, by default, not subdivided.
LilyPond Notation Reference: Reference to page numbers
In the rules above, the beam-type is the duration of the shortest note in the beamed group. We welcome your aid; please help referece by reporting errors to our bug list. For right-pointing flat flags on lone notes, use paired  beam indicators and set stemLeftBeamCount to zero see Example 1. One way to avoid this problem is to set the time signature in only one staff. Beaming patterns that differ from the automatic defaults can be created; see Setting automatic beam behavior.
The workaround for these problems is to manually beam the last beam in the voice or score.
LilyPond — Notation Reference
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. This behavior can be modified reeference subdivide the beams into sub-groups by setting the property subdivideBeams. Beam-ending rules specified in the Score context apply to all staves, but can be modified at both Staff and Voice levels:.
Manual beamsSetting automatic beam behavior.
Feathered beams are used to indicate that a small group of notes should be played at an increasing lilyponf decreasing tempo, without changing the overall tempo of the piece. If either property is set, its value will be used only once, and then it is erased. Changes in automatic beaming settings for a time signature notatino described in Time signature. They specify the number of beams to draw on the left and right side, respectively, of the next note.
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. For this, you specify the internal grouping of beats in a measure as a list of numbers in Scheme syntax before the time signature. If a score ends while an automatic beam has not been ended and is still accepting nogation, this last beam will not be typeset at all.
Such signs ease reading rhythmically complex modern music.
1. Musical notation
This means that setting the time signature in one staff will affect the beaming of the other staves as well. Beat grouping within a measure is controlled by the context property beatStructure.
Setting the time signature will reset the automatic beaming settings for the Timing context to the default behavior. 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.
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.
The first four 32nd notes gradually speed up, while the last four 32nd notes are at a constant tempo. For right-pointing nibs at the end of a run of beamed notes, set stemRightBeamCount to a positive value. If no beamExceptions rule is defined for the time signature in force, the beam placement is determined by the values of baseMoment and beatStructure. This behavior is controlled by the context property beamHalfMeasurewhich has effect only in time signatures with 3 in the numerator:.
For example, the autobeamer will not put beams over rests or bar lines, and in choral scores the beaming is often set to follow the meter of the lyrics rather than the notes. This behavior can be tuned through the auto-knee-gap property.
Grouping is a deference list indicating the grouping to be lilypohd to the beam. The spacing in the printed output represents the note durations only approximately, but the MIDI output is exact. Line breaks are normally forbidden when beams cross bar lines. By default baseMoment is set to one over the denominator of the time signature.
It must be set to a fraction giving the duration of the beam sub-group using the ly: In this example, the last f is printed with only one beam on the left side, i. Do this with paired  beam indicators alone Example 4. Beam setting changes can be limited to specific contexts. By default, baseMoment is one over the denominator of the time signature. The default beam settings for the time lilypind can also be changed, so that the desired beaming will always be used.
The beamExceptions rules are disabled by.
