Fluorescence

Fluorescence explores the interaction of static and dynamic musical materials. The core structure is designed with the mutual contrast of these two gestural characteristics, with the merging and echoing effects among each instrument.The first half of the piece is the alternation between the free section (static) and the “time-signature bounded” (dynamic) section, the high long notes of clarinet is featured as the imitation of the signals. The middle lontano section acts as a buffer or transitional passage for the whole composition.The fragmental motivic elements of the first half are now integrated and developed in the latter section. The potential huge momentum of the musical gesture is unleashed, as if the natural phenomenon of fluorescence, the music gradually climbs to its summit!The coda is characterized by solo clarinet and the strings’ sustained note.This work is commissioned by Hong Kong Composers’ Guild with the sponsorship from the CASH Music Fund in 2011.
