Robert Lopez-Hanshaw (b. 1988) is a Tucson, Arizona-based composer, researcher, and choral conductor. His music has been described as “exceptionally dramatic” (Sun News Tucson), “an important contribution” (Green Valley News), with “deep meaning behind… interesting arrangements” (Arizona Daily Star). His research on teaching microtonal choral music has been called “pragmatic” and “effective” (I Care If You Listen).

Lopez-Hanshaw’s music has been performed by the Tucson Symphony Orchestra and Chorus, Southern Arizona Symphony Orchestra and Chorus, University of Arizona Symphonic Choir, Arizona Repertory Singers, Sons of Orpheus Men’s Chorus, Tucson Arizona Boys’ Chorus, and others. Each year, he composes a new piece for the Tucson Girls’ Chorus.

Lopez-Hanshaw’s research interests include microtonal performance practice, especially choral; the convergent evolution of similar musical structures in different cultures; and an approach to the development of musical pitch systems through the lens of Evolutionary Phonology. He is the editor of the book Practical Microtones (forthcoming in 2021), a guide to microtonal composition and compilation of fingerings in a 72-tone equal division of the octave for all standard Western instruments. His articles have been published into Spanish, French and German, and can be found in the International Choral Bulletin, the University of Pittsburgh Microtonal Music Archive, I Care If You Listen, NewMusicBox, and others.

In 2017, Lopez-Hanshaw founded the chamber ensemble Camerata Sonora, which focuses on audience-involved performances of unusual or under-performed repertoire. He is a Guest Composer in Residence for the Southern Arizona Symphony Orchestra. In addition to Camerata Sonora, he currently conducts the University of Arizona Faculty-Staff Choir and the Tucson chapter of HaZamir International Jewish Teen Choir.
