Duo for piano and computer
MetadataShow full item record
Duo is a composition for piano and live electronics. The goal of this work is to integrate piano and electronic sounds by having both the piano and the electronics imitate the musical language of each other. In order to make the sonority of the piano part closer to the electronic sounds, the piano part avoids tonality and melodic expression, employing hexachord-based set class theory, block chords, zigzag figurations, large intervals, and extremely sparse textures. In addition, the piano introduces various metaphors of electronic sound in the piece; piano phrases often attempt to emphasize their gestures rather than their pitch content by rapid alteration of dynamics, use of extremes of register, and parallel motion of both hands. Similarly, in an effort to make the electronic sound closer to the piano, three approaches are taken. First, all electronic sounds are produced based on pre-recorded piano samples. Second, since pitch would be the primary vocabulary of the piano, a great deal of pitched material is employed in the electronic part. Third, in order to treat the electronic sounds as an independent instrument (not as an effect or signal processor), no real-time digital signal processing is employed; The Pd patch programmed for this work consists of piano-sample-based synthesizers and algorithms for playing them.
