He is also accompanist at Temple Israel in Boston, Temple Beth Elohim in Wellesley, Rivers School Conservatory, and Perkins School for the Blind.

He is active in the Boston chamber music scene and annually attends the Bennington Chamber Music Conference. He has studied with Darryl Rosenberg and Kevin McGinty.

William Farrell, Bass

Will Ferrell.jpgWilliam Farrell has been singing with Commonwealth Chorale as bass section leader since 2016, and he is excited to be joining the group for another season. Since moving to the Greater Boston area in fall 2015, he has performed with various professional groups, including The Boston Camerata, The Tanglewood Festival Chorus for the Boston Symphony Orchestra and the Boston Pops, Capella Nova Mundi, Canto Armonico, and St. Paul's Choir School. In 2019, he had the unique opportunity to perform at the activation Bleed for the Throne by HBO, Game of Thrones, and the American Red Cross at SXSW.

William graduated with a Master of Music in Early Music from the Longy School of Music in 2017. He loves to explore all types of historical performance, especially Renaissance polyphony and Baroque opera. Over the past year he has been on an endeavor with a few other professional singers to present rarely performed or unperformed Franco-Flemish polyphonic choral settings—one on a part—for St. Clements Eucharistic Shrine. They approach settings with liturgically appropriate texts in an attempt to survey a large portion of the repertoire that gets ignored. Outside of singing, William is an avid cyclist and loves to take any opportunity to return to New Hampshire where he can cycle on the beautiful mountain roads.
