Four Lines


Scores arranged for four different instrumentations with instruments specified by range: 1) two high and two low instruments, 2) two high instruments, 3) two pianos or other keyboards covering the piano range and 4) four trumpets; score may also be played by multiples of four instruments—for example, twelve trumpets—with parts doubled or distributed and arranged in space; parts are played in loose synchrony with electronic tracks provided on a CD; solo improvisations may be inserted at various points in the score.

The musical material was derived from studying the time line dynamics of event related potentials (ERPs) occurring in the brains of two performers during a performance of On Being Invisible II (Hypatia Speaks to Jefferson in a Dream), Frog Peak Music, Hanover, NH.
