Brian Ciach (pronounced “SIGH-ack“, born 1977) is a composer and new music pianist from Philadelphia. He is an On-Call Instructor in Music Theory at Santa Clara University and Assistant Director and Instructor of Music (Piano, Piano Improvisation, Music Theory, and Composition) at the Hunter School of Music in San Jose, California. Brian is a Music Engraver for the Subito Music Corporation. His compositions are published by Potenza Music.

His music is evocative and attractive in its imagery, often using intrepid instrumentation and imaginative formal concepts woven from a free and accessible tonal language. Dr. Ciach has written a Vegetable Requiem (2012) for hand-made vegetable ocarinas, a Second Piano Sonata (2007) that runs out of notes, and Road Trip (2010) for soprano and chamber orchestra, presenting original poetry set in two ways, as if written by two different composers. Collective Uncommon: Seven Orchestral Studies on Medical Oddities (2012), his Indiana University dissertation inspired by curiosities found in the Mütter museum, received this review after a performance by the Minnesota Orchestra: "Ciach was the composer most intent upon letting his imagination run wild all over the music (hence the cabbages and dolls), but he also had the strongest sense of how to create layers of sounds..." (Hubbard, St. Paul Pioneer Press).

Brian's music has been performed across Europe and the United States. Recent premieres of commissioned works include Rorate Caeli (2013) for SATB a cappella chorus, performed in Vienna by Chorus Delicti Wein (Vivian Ip, director) and Kentucky Folk Pieces (2013) for flute and piano performed in St. Martin-in-the-Fields Church in London and the National Concert Hall in Dublin by Linda Chatterton, flute, and Matthew McCright, piano. Chaconne for amplified cello and electronic music (2008) was performed by Roger Lebow at the 2014 Ussachevsky Memorial Festival of Electroacoustic Music at Pomona College in Claremont, California. In 2012, Brian was a participant in the Minnesota Orchestra Composer Institute, which led to that orchestra's performance of Collective Uncommon: Seven Orchestral Studies on Medical Oddities.
