Three times a year, Commonwealth Chorale has a Saturday morning workshop and rehearsal. The first half is dedicated to working with a professional singer on vocal technique generally and with examples from our current concert music preparation. Our January workshop was with well-known Boston-based tenor Gregory Zavracky. A frequent soloist with local musical groups, Mr. Zavracky is also a member of Boston Conservatory’s voice faculty. Chorus members really enjoyed learning about important general health issues important for singers such as hydration and sleep. Mr. Zavracky also introduced a suite of stretching exercises for the neck, face, and tongue as well as lip and tongue trill exercises for vocal warmup.
