[MEI-L] Anacrusis measures

[Roland, Perry D. (pdr4h)]

Hi Craig,

The @complete attribute is no longer supported. :-|

There is no method for indicating that the measure is “filled from the end”.  But one way is to use “anacrusis” instead of “upbeat” to label an incomplete measure. :-)

As is often the case, there’s more than one way to encode a “measure split by a repeat sign”.  It can be represented as a single measure with an internal, so-called “pseudo” bar line or as 2 separate and incomplete measures.  While musically (graphically?) it’s convenient to think of such a measure as a single entity, representation as 2 incomplete measures makes more sense from a structural point of view -- the “chunks” of the measure can be given an ID, assigned functions (using @type), and provided with rendering hints, independently of each other.  In addition, using 2 measure elements doesn’t break any hierarchy created by <section> and <ending> elements.  The @join attribute can be used to indicate that the 2 measures form a single logical entity.

Hi David et al.,

I encode anacrusis measures in MEI like this:

     <measure n="0" left="invis" complete="i">
      <staff n="1">
       <layer n="1">
        <note pname="d" oct="4" dur="2"/>
       </layer>
      </staff>
     </measure>

Where measure at complete="i" means that it is not a completely full measure, and measure at left="invis" is perhaps not necessary, but insinuates that it is the last part of an incomplete measure.  Comments on how to do properly or how @type="upbeat" works with this encoding or not would be good to post.

For type="upbeat" how would that related to the second half of a measure which is split by a repeat sign?

Is there an attribute for measures which says that the metric positions are filled from the end of the measure rather than the front (notice that this example has a half-note in it.  If the meter is 4/4, then that is not strictly an "upbeat" since it would be an "uptwobeat" measure.

Dear colleagues,

while encoding pickup measures I’ve found that the Sibelius to MEI plugin does not use any kind of notation for them, however I’ve found some examples among the samples in github (https://github.com/music-encoding/music-encoding/tree/MEI_dev/samples/MEI2013/), e.g. Opera.mei, that encode it using:

<measure n="0" xml:id="m0" type=“upbeat">

How should I encode anacrusis measures=

Thank you in advance,
David
