The present portfolio consists of three works: 'To the Woman Going Up The Escalator at Columbus Circle at Five-Thirty Last Evening', 'Fata Morgana' and '装配线 (Assembly Line)'. 'To the Woman Going Up the Escalator at Columbus Circle at Five-Thirty Last Evening' is a short orchestral study after a poem by Andrea Cohen. Most of the musical material is informed, to varying degrees, by the Shepard tone illusion. In addition to applying the phenomenon to the pitch material, I have attempted to translate and extend it to other parameters of the music. 'Fata Morgana' is a short work for solo piano and ensemble. The title, which refers to a type of superior mirage, was an afterthought but it captures something of the character of the music as well as its veiled or illusory quality. '装配线 (Assembly Line)' is based on a simple idea. There are two laptops – one a mac, the other a PC – and their everyday sounds (the various system sounds, start-up sounds, crash sounds, etc.) provide the raw material of the work. Interspersed with the everyday sounds of the laptops, which are mimicked by the acoustic instruments, are sounds from inside factories where the laptops are assembled (triggered by a third laptop, offstage) as well as excerpts from Apple and Microsoft commercials.
