Rococo Fantasies is a set of 11 bagatelles. Each moves from one tone centre to another, often via 'chromatic mediant' harmony (a major or minor third above or below the tone centre). Book One contains 6 of them. They endeavour to create a variety of idiosyncratic rhetorical characters by swerving between multiple metrical, thematic, and textural ideas rapidly in the course of a few measures in some of the pieces, but beavering away at just one or two (over rapidly modulating harmonic changes) in others.
