Toby Twining is an innovative American composer and musician best known for his boundary-pushing works in the realm of a cappella music, with a notable emphasis on experimental choral techniques and the exploration of microtonal tuning systems. Twining’s fascination with music began in his youth and was cultivated through his studies at Yale University, where he delved deeply into the worlds of composition and theory. In pursuing his unique artistic vision, Twining founded the Toby Twining Music ensemble in the early 1990s, a group dedicated to performing his complex and genre-defying compositions, which fuse classical harmony with modern innovation and global musical influences.

Twining's discography reflects his experimental ethos, with critical acclaim for works such as "Chrysalid Requiem" (2002), a profound requiem mass that delves into complex microtonal languages, breathing new life into the ancient form. "Eurydice" (2011) further demonstrates Twining’s narrative prowess and adventurous compositional style, telling a timeless Greek myth through a collection of otherworldly vocalizations. "Shaman: Toby Twining Music" (1993) features a range of pieces that exemplify Twining's early exploration into the extended capabilities of the human voice, incorporating techniques and sounds from various indigenous and contemporary cultures. Together, these works cement Twining’s reputation as a masterful innovator of vocal music, whose contributions continue to challenge and expand the boundaries of a cappella performance.
