Co-chair Meeting Minutes: February 18, 2020

Musikmesse meeting

We are still waiting for confirmation from the Musikmesse organisers about the meeting schedule and venue. We will continue to chase the organisers!

MNX-Common

Adrian has not yet found the time to work on the dynamics examples for the MNX-Common by Example page as discussed in the previous co-chair meeting, but will be working on this in the near future.

Adrian next plans to add tuplets to the MNX-Common by Example page. The co-chairs had a brief discussion about the necessity to support both nested tuplets and tuplets crossing barlines. Nested tuplets are accommodated by the current specification since tuplets are contained within sequences, so having multiple levels of nested tuplet does not violate the measure-sequence-tuplet hierarchy. However, tuplets crossing barlines present more of a challenge, since a tuplet element cannot, as currently specified, exist in two sequences. Partial tuplets – as used by Boulez, Adès, et al – pose a different encoding challenge.

For the time being, the co-chairs have elected to consider only complete tuplets that are fully contained within a single measure, and Adrian will develop some examples to validate the current specification.

Next meeting

The next co-chair meeting is scheduled for Tuesday 3 March 2020.
