The co-chairs discussed whether or not we should include the optional <strong>index<\/strong> attribute to each <strong>measure<\/strong> element that makes the bar number explicit, but decided to keep it as simple as possible for the purposes of this example.<\/p>\n\n\n\n<p>The co-chairs discussed the issue of multi-metric music, which requires multiple <strong>global<\/strong> elements and the assigning of specific parts to the time signatures in each global element. There was also further discussion of whether <strong>index<\/strong> should be compulsory, which would enable a sparse representation of the <strong>global<\/strong> element, i.e. only including those <strong>measure<\/strong> elements in which there is a change of time signature, but this would require making <strong>index<\/strong> compulsory and it was decided not to revisit this prior decision again now.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Octave lines<\/h3>\n\n\n\n<p>Adrian is next going to look at giving examples of octave lines in MusicXML. Octave lines are an example of a <a href=\"https:\/\/w3c.github.io\/mnx\/specification\/common\/#common-spanning-directions\" target=\"_blank\" rel=\"nofollow\">spanning element<\/a>, which appear either in the <strong>directions<\/strong> attribute of a <strong>measure<\/strong> element (if they apply to all voices) or of a <strong>sequence<\/strong> attribute (if they apply to a specific voice). We need to be clear about the <strong>end<\/strong> attribute and whether or not the note or event at that position is transposed by the octave line.<\/p>\n\n\n\n<p>Adrian will work up an example for discussion and then move to adding octave lines to the spec. This will be relevant to <a href=\"https:\/\/github.com\/w3c\/mnx\/issues\/111\" target=\"_blank\" rel=\"nofollow\">issue #111<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">MusicXML 3.2 and SMuFL 1.4 update<\/h3>\n\n\n\n<p>There was no discussion of MusicXML 3.2 or SMuFL 1.4 in this meeting.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Next meeting<\/h3>\n\n\n\n<p>The next co-chair meeting will be on 27 August 2019.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>MNX-Common by Example Adrian has added a section on time signatures to the MNX-Common by Example page to illustrate the approach MNX-Common takes to time signatures, showing how time signatures are shown in the global element.
