mei:staffDef

Color of beams, including those associated with
tuplets.

Provides an example of how automated beaming (including secondary beams)
is to be performed.

Encodes whether a beam is "feathered" and in which
direction.

Indicates whether automatically-drawn beams should include rests shorter
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.

Encodes a value for the clef symbol.

Determines whether the clef is to be displayed.

Identifies one or more metadata elements within the header, which are
understood to apply to the element bearing this attribute and its
content.

Contains a default duration in those situations when the first note, rest,
chord, etc. in a measure does not have a duration specified.

Records the default distance from the staff for dynamic
marks.

Determines whether to display guitar chord grids.

Records the default distance from the staff of harmonic indications, such
as guitar chord grids or functional labels.

Provides a way of pointing to a MIDI instrument definition. It must
contain the ID of an <instrDef> element elsewhere in the
document.

Contains an accidental for the tonic key, if one is required, e.g., if
key.pname equals 'c' and key.accid equals 's', then a tonic of C# is
indicated.

Indicates major, minor, or other tonality.

Holds the pitch name of the tonic key, e.g. 'c' for the key of
C.

Indicates where the key lies in the circle of fifths.

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.

Determines whether cautionary accidentals should be displayed at a key
change.

Provides a name or label for an element. The value may be any
string.

Provides a label for a group of staves on pages after the first page.
Usually, this label takes an abbreviated form.

Indicates the number of layers and their stem
directions.

Indicates the number of staff lines.

Captures the colors of the staff lines. The value is structured; that is,
it should have the same number of space-separated RGB values as the number of lines
indicated by the lines attribute. A line can be made invisible by assigning it the same
RGB value as the background, usually white.

Records whether all staff lines are visible.

Describes the alignment of lyric syllables associated with a note or
chord.

Sets the font family default value for lyrics.

Sets the font name default value for lyrics.

Sets the default font size value for lyrics.

Sets the default font style value for lyrics.

Sets the default font weight value for lyrics.

Records the color of the mensuration sign. Do not confuse this with the
musical term 'color' as used in pre-CMN notation.

Determines if a dot is to be added to the base symbol.

Indicates whether the base symbol is written vertically or
horizontally.

Holds the staff location of the mensuration sign.

Describes the rotation or reflection of the base
symbol.

The base symbol in the mensuration sign/time signature of mensural
notation.

Describes the relative size of the mensuration sign.

Indicates the number lines added to the mensuration sign. For example, one
slash is added for what we now call 'alla breve'.

Captures the number of beats in a measure, that is, the top number of the
meter signature. It must contain a decimal number or an additive expression that evaluates
to a decimal number, such as 2+3.

Contains an indication of how the meter signature should be
rendered.

Determines whether a new meter signature should be displayed when the
meter signature changes.

Indicates the use of a meter symbol instead of a numeric meter signature,
that is, 'C' for common time or 'C' with a slash for cut time.

Contains the number indicating the beat unit, that is, the bottom number
of the meter signature.

Describes the maxima-long relationship.

Describes the long-breve relationship.

Indicates whether programmatically calculated counts of multiple measures
of rest (mRest) and whole measure repeats (mRpt) in parts should be
rendered.

A non-negative integer value functioning as a "name".

Provides any sub-classification of the notation contained or described by
the element, additional to that given by its notationtype attribute.

Contains classification of the notation contained or described by the
element bearing this attribute.

Along with numbase.default, describes the default duration as a ratio.
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.

Determines whether piano pedal marks should be rendered as lines or as
terms.

Indicates the number of pulses (sometimes referred to as ticks or
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.

Scale factor to be applied to the feature to make it the desired display
size.

Records the absolute distance (as opposed to the relative distances
recorded in <scoreDef> elements) between this staff and the preceding one in the
same system. This value is meaningless for the first staff in a system since the
spacing.system attribute indicates the spacing between systems.

Provides a *written* pitch and octave for each open string or course of
strings.

Describes the breve-semibreve relationship.

Determines how far from the staff to render text
elements.

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

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

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

Provides a default value for the font style of text (other than lyrics)
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.

Indicates if a feature should be rendered when the notation is presented
graphically or sounded when it is presented in an aural form.

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.
