![]() between measures that is, directly within section and ending elements, and.within the description of staff groups that is, in staffGrp,.To accommodate these circumstances, in CMN staffDef is allowed to occur in the following locations: Likewise, a staff may change its clef, gain or lose layers, a score may change keys, gain or lose staves, use different layout Sometimes it is necessary to provide the parameters of a score or a staff with new Relationships between these threads from measure to measure as well as across staves, That term implies continuity across measure boundaries. MEI does not use the term ‘voice’ to describe these ‘musical threads’ because Information about key signature gathered from a staffDef for a transposing instrument.Įvery staffDef may contain a number of layerDef elements, which may be used to establish default values for the distinct layers sharing However, a section-specific scoreDef that provides only information about the meter does not override the more specific Most specific element provides this information: For example, a keySig in the preceding measure is more relevant than a staffDef at the beginning of the section, which is more relevant than a scoreDef at the beginning of the score. As a general rule, the closest preceding and Such flexibility as this may require close inspection of an encoding to retrieve theĬorrect definitions for a given staff. In chapters 11.1 Critical Apparatus and 11.2 Editorial Markup of these Guidelines. In this context, it is also possible to combine them with the elements described Overridden either by the same element bearing different information or a staffDef or scoreDef. In the layer context they function as milestones and affect all following contentĪssigned to the layer (even in subsequent measures) until their information is again With the exception of label, these elements may also occur within the flow of musical events captured in a layer, since they are members of model.eventLike. (meter signature group) – Used to capture alternating, interchanging, and mixed meter In addition to the parameters inherited from scoreDef, the following attributes are important for staffDef elements: Have to mimic the order of the staffDef elements with scoreDef. Therefore, the encoding order of staves within a measure does not Staff elements within a measure refer to these staffDef declarations using their own n attribute values. The order of staffDef elements within scoreDef follows the order of staves in the source document or planned rendering. The first occurence of a staffDef with a given number must also indicate the number of staff lines via the lines attribute. The label and labelAbbr subelements may be used for providing staff labels for the first and subsequent systems.Įvery staffDef must have an n attribute with an integer as its value. It bears most of the attributes described above. Of that group or only on the staves themselves.Ī staffDef element is used to describe an individual staff of a score or performer part. ![]() The bar.thru attribute on staffGrp allows one to specify whether barlines are drawn across the space between staves The staffGrp element is also used for the two staves of a grand staff. This is useful for collecting instrumental or vocal groups in a large score, suchĪs woodwinds, brasses, etc., and for assigning a shared label to the group, using This element is used to gather individual staves and other staff groups. When content is provided for scoreDef, it must contain a staffGrp element. These are available from the element definitions accessible at scoreDef, staffDef, staffGrp and layerDef. There are other attributes that allow the specification of many further details ofĪ score. Sets the default font size value for lyrics.
