Our award-winning youth chorus Throckappella, directed by the multi-talented Tim Silva, is an advanced vocal music program for talented high school students who share a love of music and are motivated to advance their skills in repertoire, performance and ensemble skills. High school age singers are chosen thru audition and merit based on talent, ability, dedication, a cooperative spirit, and a love of music.  The group has many performance opportunities throughout the year that allow them to expand their talents in front of an audience.

Students can expect to develop and deepen their understanding of:

  • Healthy singing, breathing technique, and good vocal habits
  • Body awareness as it pertains to performers, specifically vocalists_ona8372
  • Intonation, harmony, and musicality
  • Vocal repertoire from several different time periods and cultures;
  • A number of learning styles for music (i.e. classical western notation, lead sheets, learning by ear)
  • Western notation and tonal theory (students will arrange music for the ensemble to sing)
  • How to cooperate and work as a team toward ensemble goals
  • Teamwork, commitment, self-discipline, and respect

An East Bay native, Tim Silva is an active performer, teacher, and collaborator in a wide range of settings. Since completing degrees in composition and vocal music education, Tim has recorded with some of the Bay Area’s most elite chamber choruses (AVE, Volti, SF Choral Artists) as well on the debut albums of Briget Boyle and Nick Hours. This summer, he made his debut with Chalice Consort and also sang with the Russian National Orchestra in Volti’s Festival Chorus. He performs regularly with several independent artists as a drummer/vocalist/multi-instrumentalist, and also is one-third of the folk-pop trio Iron Henry. He teaches group classes, and private lessons in general music, choral music, music theory, and vocal technique to preschoolers, senior citizens, and everyone in between.

It is our hope that young artists at Throckmorton will not only be influenced by our rich artistic community but that they, themselves will be an influence on that community.  Each year Throckappella’s talented group of singers engage and enrich our community as well as the wider Bay Area community and beyond.
