Syzygy is a jazz composition by Michael Brecker, written for and first recorded on his self-titled debut album in 1987. The piece opens with a tenor saxophone and drums duet before the full ensemble enters with the stated theme, establishing a balance between written material and substantial room for improvisation. The composition displays polymetric and rhythmic sophistication, with a structural design that preserves specific rhythmic and harmonic frameworks during the solo sections rather than dissolving into open vamps. This approach, reminiscent of the compositional method found in pieces like Herbie Hancock's Maiden Voyage, allows musicians to develop ideas within disciplined boundaries while maintaining the composed architecture of the piece. Syzygy also showcases Brecker's interest in orchestration and instrumental color, featuring different instrumental voices and textures throughout its nearly ten-minute duration. The composition provided a platform for Brecker's pioneering work on the EWI, the Electronic Wind Instrument he helped popularize in jazz contexts, with an overdubbed unison section on the instrument that highlights his technical and compositional ambitions. Written during sessions co-produced by Don Grolnick, Syzygy brought together musicians from Pat Metheny's landmark 80/81 album, creating an ensemble with established musical rapport. The piece has attracted attention from jazz educators and transcribers as an important example of contemporary jazz composition, though it has not entered the widely performed standard repertoire.
