William Peacock is an American composer and singer. William is a Massachusetts native, and was born in Quincy, Massachusetts, but has spent most of his life living in Braintree, Massachusetts. William is a recent graduate of Boston University, where he obtained a Bachelor's of Music, majoring in Vocal Performance and Composition and Theory. William also recently began his studies as a Master of Composition, also at Boston University. 

William is both a tenor and countertenor, and is a frequent singer in the Boston choral scene. William's recent engagements as a singer include a concert series with Triad: Boston Choral Collective, a concert series with Ensemble Altera, a rising New England based ensemble, and as a tenor soloist for a performance of Monteverdi's Vespers with Analog Chorale. As a composer, William was recently nominated as a finalist for the international Young Composers Competition. William is also a two time recipient of Boston University's Wainwright Prize for composition, in the category of a "song composed on a sonnet".

William typically writes music for smaller ensembles, including chamber works, solo works, and art song, though he has written a number of large scale works as well. Stylistically, William utilizes lyricism among polytonal, freely atonal, and non-functional harmonic contexts, along with often biting rhythmic vitality. William's musical language is often presented in tandem with a complex (and often unnervingly humorous) emotional palette, and is displayed through a critical lens of the social climate at large. As such, the subject matter of these works often pertain to politics and social justice in the modern world. 

William’s recent projects include the recent premiere of his Four Fantasy Pieces for flute, Bb clarinet, and bassoon, the upcoming premiere of a song cycle for mezzo-soprano and piano showcasing poetry by Darío Espina Pérez (delayed by COVID-19), and the recent premiere by the Mivos string quartet of his work Repeated Friction, as well as the recent premiere of a brief solo a capella work for soprano by contemporary vocalist Stephanie Lamprea titled Allergies Not So Bad.
