Bebop Riddle IIB is by turns sprightly, spry, energetic and spirited. Thomas crafted animated, traveling, flexible, versatile, changing, fluid and buoyant sonic adventures. Iridescent, bold and scintillating, the carefully sculpted and fashioned musical materials of Bebop Riddle IIB are agile and vivacious, and their flexibility allows pathways to braid harmonic, rhythmic and contrapuntal elements that are constantly transformed - at times whimsical, jazzy and be-bop-like, layered and reverberating, with lyrical resonance, pirouettes, fulcrum points and vitality. The two equally virtuosic parts, which require highly characterized dynamics and articulations, bubble forth for 8 minutes and 15 seconds, unfolding continuously developing phrases. The music is organic and, at every level, concerned with transformations and connections. Bassoon can be substituted by baritone saxophone or bass clarinet. The range of the bassoon part is C2 to E5.
