The term “song” or “song session” describes the elaborate vocalization structure produced by humpback whales. Song Sessions connects whale and human music. Employing flutes, clarinets, sine-tones, and an LED light installation, four improvisers perform an ever-changing work based on the structure of whale songs. Each performance is unique and distinctive. With flutes played by Isabel Lepanto Gleicher and clarinets played by Eric Umble, the duo improvises as two whales communicating over a vast ocean. The sine-tones, played by Barry Sharp, provide an evolving ambiance that comprises frequencies of oceanic noise pollution. Lastly, Paige Seber utilizes an adaptable light installation manipulated to mimic the ocean in flux and respond in real-time to the performance's dramatic arc.
