Module
MEI.shared
Attributes
head.altsym, head.auth, head.color, head.fill, head.fillcolor, head.mod, head.rotation, head.shape, head.visible
head.altsym(optional)Provides a way of pointing to a user-defined symbol. It must contain a reference to an ID of a symbolDef element elsewhere in the document. Value conforms to data.URI.
<att.noteHeads>direct children@head.altsym
head.auth(optional)A name or label associated with the controlled vocabulary from which a numerical value of head.shape is taken. Suggested values are: "smufl" (Standard Music Font Layout.)
<att.noteHeads>direct children@head.auth
head.color(optional)Captures the overall color of a notehead. Value conforms to data.COLOR.
<att.noteHeads>direct children@head.color
head.fill(optional)Describes how/if the notehead is filled. Value conforms to data.FILL.
<att.noteHeads>direct children@head.fill
head.fillcolor(optional)Captures the fill color of a notehead if different from the overall note color. Value conforms to data.COLOR.
<att.noteHeads>direct children@head.fillcolor
head.mod(optional)Records any additional symbols applied to the notehead. One or more values from data.NOTEHEADMODIFIER, separated by spaces.
<att.noteHeads>direct children@head.mod
head.rotation(optional)Describes rotation applied to the basic notehead shape. A positive value rotates the notehead in a counter-clockwise fashion, while negative values produce clockwise rotation. Value conforms to data.ROTATION.
<att.noteHeads>direct children@head.rotation
head.shape(optional)Used to override the head shape normally used for the given duration. Value conforms to data.HEADSHAPE.
<att.noteHeads>direct children@head.shape
head.visible(optional)Indicates if a feature should be rendered when the notation is presented graphically or sounded when it is presented in an aural form. Value conforms to data.BOOLEAN.
<att.noteHeads>direct children@head.visible
head.altsym(optional)Provides a way of pointing to a user-defined symbol. It must contain a reference to an ID of a symbolDef element elsewhere in the document. Value conforms to data.URI.
head.auth(optional)A name or label associated with the controlled vocabulary from which a numerical value of head.shape is taken. Suggested values are: "smufl" (Standard Music Font Layout.)
head.color(optional)Captures the overall color of a notehead. Value conforms to data.COLOR.
head.fill(optional)Describes how/if the notehead is filled. Value conforms to data.FILL.
head.fillcolor(optional)Captures the fill color of a notehead if different from the overall note color. Value conforms to data.COLOR.
head.mod(optional)Records any additional symbols applied to the notehead. One or more values from data.NOTEHEADMODIFIER, separated by spaces.
head.rotation(optional)Describes rotation applied to the basic notehead shape. A positive value rotates the notehead in a counter-clockwise fashion, while negative values produce clockwise rotation. Value conforms to data.ROTATION.
head.shape(optional)Used to override the head shape normally used for the given duration. Value conforms to data.HEADSHAPE.
head.visible(optional)Indicates if a feature should be rendered when the notation is presented graphically or sounded when it is presented in an aural form. Value conforms to data.BOOLEAN.
Component declarations that are shared between two or more modules.
head.altsym(optional)Provides a way of pointing to a user-defined symbol. It must contain a reference to an ID of a symbolDef element elsewhere in the document. Value conforms to data.URI.
head.auth(optional)A name or label associated with the controlled vocabulary from which a numerical value of head.shape is taken. Suggested values are: "smufl" (Standard Music Font Layout.)
head.color(optional)Captures the overall color of a notehead. Value conforms to data.COLOR.
head.fill(optional)Describes how/if the notehead is filled. Value conforms to data.FILL.
head.fillcolor(optional)Captures the fill color of a notehead if different from the overall note color. Value conforms to data.COLOR.
head.mod(optional)Records any additional symbols applied to the notehead. One or more values from data.NOTEHEADMODIFIER, separated by spaces.
head.rotation(optional)Describes rotation applied to the basic notehead shape. A positive value rotates the notehead in a counter-clockwise fashion, while negative values produce clockwise rotation. Value conforms to data.ROTATION.
head.shape(optional)Used to override the head shape normally used for the given duration. Value conforms to data.HEADSHAPE.
head.visible(optional)Indicates if a feature should be rendered when the notation is presented graphically or sounded when it is presented in an aural form. Value conforms to data.BOOLEAN.

Constraints

@head.altsym attribute should have content.
The value in @head.altsym should correspond to the @xml:id attribute of a symbolDef element.
When @head.auth matches 'smufl', @head.shape must contain a numeric glyph reference in hexadecimal notation, like "#xE000" or "U+E000".
SMuFL version 1.18 uses the range U+E000 - U+ECBF.
