Are you composing? What are you up to? In principal, yes, but there are all these loose ends... There are always several projects on my desk, in various stages of progress. Some are compositional projects, others pre-compositional or even theoretical. One compositional project is, in principle, finished, a piece with a very large number of possible realizations through combinatorial excess, but I've decided not to let it go until I've played through a number of those realizations to my own satisfaction, which has meant picking up the clarinet for the first time in decades and seeing if the music lies under the fingers well. One "theoretical" project was a fictional reconstruction of tonality in which, depending upon the number of active voices, everything depended upon minimal voice leadings from the three perfectly even divisions of the octave.
