Unlike TAB, a jianpu sign does not correspond to a visual clef notation.
|
| color |
The color type indicates the color of an element. Color may be represented as hexadecimal RGB triples, as in HTML, or as hexadecimal ARGB tuples, with the A indicating alpha of transparency. An alpha value of 00 is totally transparent; FF is totally opaque. If RGB is used, the A value is assumed to be FF. For instance, the RGB value "#800080" represents purple. An ARGB value of "#40800080" would be a transparent purple. As in SVG 1.1, colors are defined in terms of the sRGB color space (IEC 61966).

The enclosure-shape type describes the shape and presence / absence of an enclosure around text or symbols. A bracket enclosure is similar to a rectangle with the bottom line missing, as is common in jazz notation.
|
| ending-number |
The ending-number type is used to specify either a comma-separated list of positive integers without leading zeros, or a string of zero or more spaces. It is used for the number attribute of the ending element. The zero or more spaces version is used when software knows that an ending is present, but cannot determine the type of the ending.
|
| fan |
The fan type represents the type of beam fanning present on a note, used to represent accelerandos and ritardandos.
|

|
| start-note |
The start-note type describes the starting note of trills and mordents for playback, relative to the current note.
|
| start-stop |
The start-stop type is used for an attribute of musical elements that can either start or stop, such as tuplets. The values of start and stop refer to how an element appears in musical score order, not in MusicXML document order. An element with a stop attribute may precede the corresponding element with a start attribute within a MusicXML document. This is particularly common in multi-staff music. For example, the stopping point for a tuplet may appear in staff 1 before the starting point for the tuplet appears in staff 2 later in the document.
|
| start-stop-change-continue |
The start-stop-change-continue type is used to distinguish types of pedal directions.
|
| start-stop-continue |
The start-stop-continue type is used for an attribute of musical elements that can either start or stop, but also need to refer to an intermediate point in the symbol, as for complex slurs or for formatting of symbols across system breaks. The values of start, stop, and continue refer to how an element appears in musical score order, not in MusicXML document order. An element with a stop attribute may precede the corresponding element with a start attribute within a MusicXML document. This is particularly common in multi-staff music. For example, the stopping point for a slur may appear in staff 1 before the starting point for the slur appears in staff 2 later in the document.
|
| start-stop-discontinue |
The start-stop-discontinue type is used to specify ending types. Typically, the start type is associated with the left barline of the first measure in an ending. The stop and discontinue types are associated with the right barline of the last measure in an ending. Stop is used when the ending mark concludes with a downward jog, as is typical for first endings. Discontinue is used when there is no downward jog, as is typical for second endings that do not conclude a piece.
|
| start-stop-single |
The start-stop-single type is used for an attribute of musical elements that can be used for either multi-note or single-note musical elements, as for tremolos.

The symbol-size type is used to indicate full vs. cue-sized vs. oversized symbols. The large value for oversized symbols was added in version 1.1.
|
| tenths |
The tenths type is a number representing tenths of interline staff space (positive or negative). Both integer and decimal values are allowed, such as 5 for a half space and 2.5 for a quarter space. Interline space is measured from the middle of a staff line. Distances in a MusicXML file are measured in tenths of staff space. Tenths are then scaled to millimeters within the scaling element, used in the defaults element at the start of a score. Individual staves can apply a scaling factor to adjust staff size. When a MusicXML element or attribute refers to tenths, it means the global tenths defined by the scaling element, not the local tenths as adjusted by the staff-size element.
|
| text-direction |
The text-direction type is used to adjust and override the Unicode bidirectional text algorithm, similar to the W3C Internationalization Tag Set recommendation. Values are ltr (left-to-right embed), rtl (right-to-left embed), lro (left-to-right bidi-override), and rlo (right-to-left bidi-override). The default value is ltr. This type is typically used by applications that store text in left-to-right visual order rather than logical order. Such applications can use the lro value to better communicate with other applications that more fully support bidirectional text.
|
| time-only |
The time-only type is used to indicate that a particular playback-related element only applies particular times through a repeated section. The value is a comma-separated list of positive integers arranged in ascending order, indicating which times through the repeated section that the element applies.

The time-relation type indicates the symbol used to represent the interchangeable aspect of dual time signatures.
|
| time-separator |
The time-separator type indicates how to display the arrangement between the beats and beat-type values in a time signature. The default value is none. The horizontal, diagonal, and vertical values represent horizontal, diagonal lower-left to upper-right, and vertical lines respectively. For these values, the beats and beat-type values are arranged on either side of the separator line. The none value represents no separator with the beats and beat-type arranged vertically. The adjacent value represents no separator with the beats and beat-type arranged horizontally.
|
| time-symbol |
The time-symbol type indicates how to display a time signature. The normal value is the usual fractional display, and is the implied symbol type if none is specified. Other options are the common and cut time symbols, as well as a single number with an implied denominator. The note symbol indicates that the beat-type should be represented with the corresponding downstem note rather than a number. The dotted-note symbol indicates that the beat-type should be represented with a dotted downstem note that corresponds to three times the beat-type value, and a numerator that is one third the beats value.
|
| tip-direction |
The tip-direction type represents the direction in which the tip of a stick or beater points, using Unicode arrow terminology.

| upright-inverted |
The upright-inverted type describes the appearance of a fermata element. The value is upright if not specified.
|
| valign |
The valign type is used to indicate vertical alignment to the top, middle, bottom, or baseline of the text. Defaults are implementation-dependent.
|
| valign-image |
The valign-image type is used to indicate vertical alignment for images and graphics, so it does not include a baseline value. Defaults are implementation-dependent.
|
| wedge-type |
The wedge type is crescendo for the start of a wedge that is closed at the left side, diminuendo for the start of a wedge that is closed on the right side, and stop for the end of a wedge. The continue type is used for formatting wedges over a system break, or for other situations where a single wedge is divided into multiple segments.
|
| winged |
The winged attribute indicates whether the repeat has winged extensions that appear above and below the barline. The straight and curved values represent single wings, while the double-straight and double-curved values represent double wings. The none value indicates no wings and is the default.
|
| wood |
The wood type represents pictograms for wood percussion instruments. The maraca and maracas values distinguish the one- and two-maraca versions of the pictogram. The vibraslap and castanets values are in addition to Stone's list.
|
| yes-no |
The yes-no type is used for boolean-like attributes. We cannot use W3C XML Schema booleans due to their restrictions on expression of boolean values.
|
| yes-no-number |
The yes-no-number type is used for attributes that can be either boolean or numeric values.
|
| yyyy-mm-dd |
Calendar dates are represented yyyy-mm-dd format, following ISO 8601. This is a W3C XML Schema date type, but without the optional timezone data.
