John Muniz is a composer, music theorist, speaker, and pianist, and serves as Associate Professor of Music Theory at the University of Arizona. He frequently collaborates with members of the Tucson Symphony Orchestra, University of Arizona music faculty, and pianist Anna Kijanowska on new works for voice, chamber ensemble, and piano. His music has been commissioned by Chamberhood, an affiliated ensemble of Arizona Friends of Chamber Music, and has been recorded by Anna Kijanowska for the DUX label.

An artist and scholar, Muniz regularly gives public talks on music. He has published research in leading journals including Music Theory Spectrum and Music Analysis. His work is united by a common thread: the instability of categories musicians often take for granted, from enharmonic pitch identity and extended chromatic tonality to the perception of rhythm, the theory of metal music, and the philosophical foundations of music theory itself.

He holds a PhD in Music Theory from Yale University, an MM in Composition from Boston University, and a BA in Composition from the College of William & Mary. His principal teachers include Paul Zeigler, Sophia Serghi, Joshua Fineberg, and Martin Amlin.

Current projects include a song cycle on Rilke's Sonnets to Orpheus for baritone Andrew Stuckey, a musical setting of a children's book by Tucson author Enrique Aldana, and new works created in collaboration with violinist and violist Emily Chao.
