Complexity: sorry, Lisa, not quite yet.
Okay, I'm not quite done with complexity yet. As indicated in the last post, complexity, for better or worse or (mostly) in-between, can describe a number of musical qualities or characteristics. When used in connection with something very specific, especially countable items (notes on a page, for example), the aspect of complexity described can acquire a quantitative dimension and make comparisons within and without a piece of work possible; also, when a clear process is used in composition, one might speak usefully in terms of a measurable computational complexity (which, of course, has its own complications, indeed uncertainties, which many others online can describe much more credibly). However, some of the most important forms of musical complexity are far less easily reducible to the quantitative, and some methods, while quantifiable, as often not particularly relevant when quantified to any actual music. Among these forms (incomplete, I'm sure, off the top of my hea...
