GMCLA presents three main performance series each year in December, March, and June, with three to four shows in each series. Throughout the year, we have several community performances at schools and various public and private events.

Our regular rehearsals are every Monday, 7–10pm. Rehearsal dates are usually adjusted for legal holidays. We also generally rehearse one Sunday afternoon per month, which is sometimes accompanied by a social activity. In the spring, we have a weekend-long retreat, usually in Malibu. Two or three extra rehearsals are scheduled during the week before a main performance. You will receive a complete schedule of rehearsals, performances and other important dates as soon as you join, so you can mark your calendar accordingly. Our rehearsal time is valuable: we learn a great deal of music for each concert. Therefore, many members come to rehearsal early in order to take care of business matters and to socialize. Because we strive for the best artistic product possible, GMCLA has an attendance policy which allows no more than three absences during each concert period. You will be expected to review your music on your own, so you will be fully prepared for concerts. We also prepare an inexpensive rehearsal disc for each concert with which you can practice.

Finally, GMCLA involves more than just music. To keep the Chorus running smoothly, we rely on members to volunteer extra time. The majority of jobs require relatively little time individually. As a whole, they represent a tremendous amount of effort, without which the Chorus would not be able to function.
