than a quarter note duration.

Captures beam slope.

Describes the color of the clef.

Records the amount of octave displacement to be applied to the
clef.

Records the direction of octave displacement to be applied to the
clef.

Contains a default value for the position of the clef. The value must be
in the range between 1 and the number of lines on the staff. The numbering of lines starts
with the lowest line of the staff.

Mixed key signatures, e.g. those consisting of a mixture of flats and
sharps (Read, p. 143, ex. 9-39), and key signatures with unorthodox placement of the
accidentals (Read, p. 141) must be indicated by setting the key.sig attribute to 'mixed'
and providing explicit key signature information in the key.sig.mixed attribute or in the
<keySig> element. It is intended that key.sig.mixed contain a series of tokens with
each token containing pitch name, accidental, and octave, such as 'a4 c5s e5f' that
indicate what key accidentals should be rendered and where they should be
placed.

Indicates whether the key signature should be
displayed.

always defined as a quarter note, *not the numerator of the time signature or the
metronomic indication*.

Records a MIDI channel value.

Specifies the 'on' part of the duty cycle as a percentage of a note's
duration.

Records the number of microseconds per *quarter note*. In MIDI, a beat is
always defined as a quarter note, *not the numerator of the time signature or the
metronomic indication*. At 120 quarter notes per minute, each quarter note will last
500,000 microseconds.

Sets the MIDI port value.

Sets the MIDI track.

Used to describe tempo in terms of beats (often the meter signature
denominator) per minute, ala M.M. (Maezel's Metronome). Do not confuse this attribute with
midi.bpm or midi.mspb. In MIDI, a beat is always defined as a quarter note, *not the
numerator of the time signature or the metronomic indication*.

num.default is the first value in the ratio.

Along with num.default, describes the default duration as a ratio.
numbase.default is the second value in the ratio.

Contains a default octave specification for use when the first note, rest,
chord, etc. in a measure does not have an octave value specified.

Determines the placement of notes on a 1-line staff. A value of 'true'
places all notes on the line, while a value of 'false' places stems-up notes above the
line and stems-down notes below the line.

Indicates whether staves without notes, rests, etc. should be displayed.
When the value is 'true', empty staves are displayed.

divisions) per quarter note. Unlike MIDI, MEI permits different values for a score and
individual staves.

Describes the semibreve-minim relationship.

Together, proport.num and proport.numbase specify a proportional change as
a ratio, e.g., 1:3. Proport.num is for the first value in the ratio.

Together, proport.num and proport.numbase specify a proportional change as
a ratio, e.g., 1:3. Proport.numbase is for the second value in the
ratio.

Describes the enclosing shape for rehearsal marks.

Describes a note's spacing relative to its time value.

Describes the note spacing of output.

Specifies the minimum amount of space between adjacent staves in the same
system; measured from the bottom line of the staff above to the top line of the staff
below.

Describes the space between adjacent systems; 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.

Indicates whether the staves are joined at the left by a continuous line.
The default value is "true". Do not confuse this with the heavy vertical line used as a
grouping symbol.

Describes the amount of whitespace at the left system margin relative to
page.leftmar.

Describes the amount of whitespace at the right system margin relative to
page.rightmar.

Describes the distance from page's top edge to the first system; used for
first page only.

If takt bar lines are to be used, then the taktplace attribute may be used
to denote the staff location of the shortened bar line. The location may include staff
lines, spaces, and the spaces directly above and below the staff. The value ranges between
0 (just below the staff) to 2 * number of staff lines (directly above the staff). For
example, on a 5-line staff the lines would be numbered 1,3,5,7, and 9 while the spaces
would be numbered 0,2,4,6,8,10. For example, a value of '9' puts the bar line through the
top line of a 5-line staff.

Describes the breve-semibreve relationship.

Determines how far from the staff to render text
elements.

when this information is not provided on the individual elements.

Provides a default value for the font weight for text (other than lyrics)
when this information is not provided on the individual elements.

Records the amount of diatonic pitch shift, e.g., C to C♯ = 0, C to D♭ =
1, necessary to calculate the sounded pitch from the written one.

Records the amount of pitch shift in semitones, e.g., C to C♯ = 1, C to D♭
= 1, necessary to calculate the sounded pitch from the written one.

Holds a value for cycles per second, i.e., Hertz, for a tuning reference
pitch.

Holds the pitch name of a tuning reference pitch.

Provides an indication of the tuning system, 'just', for
example.

Defines the height of a "virtual unit" (vu) in terms of real-world units.
A single vu is half the distance between the vertical center point of a staff line and
that of an adjacent staff line.

Provides a base URI reference with which applications can resolve relative
URI references into absolute URI references.

Regularizes the naming of an element and thus facilitates building links
between it and other resources. Each id attribute within a document must have a unique
value.
