The first and last compositions on Fugu were written for choreographer and dancer Li Chiao-Ping, although they have not yet been performed as dances. All but one of the pieces use varying compound time signatures and all are based on Stephen Dembski's post-serial tonal organization system. In fact, this is the most cohesive representation of that system as an nside the changes alternative to traditional jazz improvisation. Although many of Fields other compositions rely on Dembski's system, in these other cases the pitch sets are used just as sets rather than as interwoven chords and scales.
