Throckmorton Chorus


Throckmorton Chorus, inspired by Bay Area master accompanist, teacher and composer Joe Bloom, was formed in January 2014 to foster and share the art of choral music and offer an educational process that focuses on the pursuit of choral excellence in repertoire and performance.  Today it is composed of about 30 singers from all ages and walks of life who share a love of music and a desire to learn and grow in collaboration with others.   Each season the repertoire includes a wide variety of styles allowing members to expand and deepen their skills and understanding of this rich music.  The quality and artistry of the chorus, under the direction of Richard McKinley, continues to grow each season by leaps and bounds.

Rehearsals are held on Monday nights and each season culminates in a public concert at the theatre.  The group is offered other seasonal opportunities to perform and contribute to the thriving artistic environment around us. Membership is by audition and subject to availability in your voice section.  Auditions for new members are held twice a year – in January/February and September. Returning members re-audition each September before the Fall season.


Auditions will be held Monday, February 5th, 6th and 7th, 2018.


Rehearsals will begin February 12 and run thru May 14th, 2018.

Spring Concert

The chorus will have their Spring Concert on Wednesday May 16 at 8pm.
