A description of how to encode cue-sized notes in **kern spines.

Cue-sized notes are smaller than regular notes, similar to grace notes; however, unlike grace notes, cue-sized notes possess non-zero score durations. Cue-sized notes can be encoded in two ways within **kern spines. For occasional cue-sized notes, an RDF record can be added to mark individual notes as being cue-sized:

**kern

*^
4g	8gN\L
.	8aNJ
*v	*v
4b
=
*-
!!!RDF**kern: N = cue size

For generating a longer sequence of cue-sized notes, a second method using *cue and *Xcue tandem interpretations can be used to turn on/off cue-size:

**kern	**kern
*clefF4	*clefG2
*M3/4	*M3/4
=	=
*	*Xtuplet
*	*cue
*	*rscale:2

The *cue and *Xcue markers only apply to a specific subspine of music, so one subspine can be cue sized while another is not. This is useful for adding cues to orchestra parts.
