2.4.4 Line Rendition
Module
MEI.shared
Attributes
lform, lsegs, lwidth
lform(optional)Describes the style of a line. Value conforms to data.LINEFORM.
<att.lineRend.base>direct children@lform
lsegs(optional)Describes the number of segments into which a dashed or dotted line may be divided, or the number of "peaks" of a wavy line; a pair of space-separated values (minimum and maximum, respectively) provides a range between which a rendering system-supplied value may fall, while a single value indicates a fixed amount of space; that is, the minimum and maximum values are equal. One or two values of datatype a positive integer no smaller than 2, separated by a space.

lwidth(optional)Width of a line. Value conforms to data.LINEWIDTH.
<att.lineRend.base>direct children@lwidth
lform(optional)Describes the style of a line. Value conforms to data.LINEFORM.
lwidth(optional)Width of a line. Value conforms to data.LINEWIDTH.

Available at
phraseIndication of 1) a "unified melodic idea" or 2) performance technique.
attaccaAn instruction to begin the next section or movement of a composition without pause.
dirAn instruction expressed as a combination of text and symbols, typically above, below, or between staves, but not on the staff — that is not encoded elsewhere in more specific elements, like tempo, dynam or repeatMark.
dynamIndication of the volume of a note, phrase, or section of music.
fSingle element of a figured bass indication.
fingAn individual finger in a fingering indication.
fingGrpA group of individual fingers in a fingering indication.
harmAn indication of harmony, e.g., chord names, tablature grids, harmonic analysis, figured bass.
octaveAn indication that a passage should be performed one or more octaves above or below its written pitch.
repeatMark An instruction expressed as a combination of text and symbols – segno and coda – typically above, below, or between staves, but not on the staff.
tempoText and symbols descriptive of tempo, mood, or style, e.g., "allarg.", "a tempo", "cantabile", "Moderato", "♩=60", "Moderato ♩ =60").
trillRapid alternation of a note with another (usually at the interval of a second above).
bracketSpanMarks a sequence of notational events grouped by a bracket.
endingAlternative ending for a repeated passage of music; i.e., prima volta, seconda volta, etc.
glissA continuous or sliding movement from one pitch to another, usually indicated by a straight or wavy line.
pedalPiano pedal mark.
arpegIndicates that the notes of a chord are to be performed successively rather than simultaneously, usually from lowest to highest. Sometimes called a "roll".
bendA variation in pitch (often micro-tonal) upwards or downwards during the course of a note.
curveA curved line that cannot be represented by a more specific element, such as a slur.
hairpinIndicates continuous dynamics expressed on the score as wedge-shaped graphics, e.g., < and >.
lvA "tie-like" indication that a note should ring beyond its written duration.
slurIndication of 1) a "unified melodic idea" or 2) performance technique.
tieAn indication that two notes of the same pitch form a single note with their combined rhythmic values.
Common Music Notation (CMN) repertoire component declarations.
