I’m grateful to Greenleaf’s Michael Bates for drawing my attention to practicesightreading.com, an incredibly cool random rhythm generator that supports multiple levels of complexity, and both single and mixed meters. As the name of the site suggests, it’s intended to generate customized exercises for rhythmic sight-reading, but the compositional possibilities of a user-configurable random rhythm generator like this shouldn’t be overlooked either.

My only quibbles so far is that it would be nice to be able to input any time sig instead of being limited to preset choices (also, I really want to turn off display of the metric subdivisions for 5/8 and 7/8), and everything is very downbeat-centric — there are not nearly enough tied notes, even at the highest levels.
