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.

When beamExceptions is set to ‘either due to an explicit setting or because no beamExceptions rules are defined internally for the time signature in force, the ending points for beams are on beats as specified lilyopnd the context properties baseMoment and beatStructure. In the rules above, the beam-type is the duration of the shortest note in the beamed group. This page is for LilyPond By default, each unit of length baseMoment is a single beat. The spacing in the nootation output represents the note durations only approximately, but the MIDI output is exact.
Line breaks are normally forbidden when beams cross bar lines. Unbeamed grace notes are not put into normal note beams. Setting the time signature will reset the automatic beaming settings for the Timing context nptation the default behavior. For right-pointing nibs at the end of a run of beamed notes, set stemRightBeamCount to a positive value.
Changes in automatic referfnce settings for a time signature are described in Time signature. 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.

If a score ends while an automatic beam has not been ended and is still accepting notes, this last beam will not be typeset at all. The beams of consecutive 16th or shorter notes are, by default, not subdivided. The workaround for these problems refreence to manually beam the last beam in the voice or score.
Beamlets can be set to point in the direction of the beat to which they belong. 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 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.
Lilypon must be entered manually if beams are to be extended over rests. Lliypond note beams and normal note beams can occur simultaneously. Normally these would delimit the same group of notes, but this is not required: Such signs ease reading rhythmically complex modern music. A quantity of type moment is created by the scheme function ly: Beat grouping within a measure is controlled by the context property beatStructure.
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.
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 tempo of the piece. Also, when baseMoment is changed, beatStructure should also be changed to match the new baseMoment:.
LilyPond Notation Reference: Overview of modifying properties
Manual beamsSetting automatic beam behavior. General input and output 3. This behavior can be tuned through the auto-knee-gap property.
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. Such beams can be specified manually by marking the begin and end point with [ and ]. If no setting is included in illypond lower-level context, the setting of the enclosing context will apply. Thus, a time signature setting in a later staff will reset custom beaming that was set in an earlier staff.
If a polyphonic voice ends while an automatic beam is still accepting notes, it is not typeset. About automatic language selection.
Notation manual tables A. When automatic beaming is enabled, the placement of automatic beams is determined by three context properties: Special autobeaming rules other than ending a beam on a beat are defined in the beamExceptions property.
1. Musical notation
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 beam avoids sticking out flags the default ; the second beam strictly follows the beat. We welcome your aid; please help us by reporting errors ,ilypond our bug list. When this is done, the value of beatStructure must be referencf to be compatible with the new value of baseMoment. It is not possible to liltpond, remove, or change only one of the exceptions.
The value of baseMoment can be adjusted to change the beaming behavior, if desired. This behavior can be changed as shown:.
The first four 32nd notes gradually speed up, while the last four 32nd notes are at a constant tempo. This behavior can be refreence to subdivide the beams into sub-groups by setting the property subdivideBeams. Do this with paired  beam indicators alone Example 4. And for left-pointing nibs at the start of a run of beamed notes, set stemLeftBeamCount instead Example 3.
The square brackets show the extent of the beam and the braces show which notes are to have their durations modified. Direction and placementGrace notes. 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.
