Whether you're a seasoned choral singer or a total beginner, an avid concert-goer or a first-time audience member—Lacuna Arts has something for you.


This a cappella chorus of 24–32 balanced voices is divided into two SATB choirs to tackle some of the more demanding 8-part choral literature.

Past repertoire has included Rheinberger's Mass in E-flat, Parry's Songs of Farewell, The Peaceable Kingdom by Randall Thompson, and double choir motets by Gabrieli, Telemann, and J.S. Bach.



For those wanting to learn more about reading music, singing technique, and historical performance practice, we offer a number of choral workshops throughout the year.

Participating in one of our workshops is a great way to gain choral experience, prepare for an audition, or discover new repertoire.


Our smaller chamber group Ensemble encourages individual responsibility with as few as 1–2 voices per part.

Past repertoire has included Victoria’s Missa Ave maris stella, the 10-voice Stabat Mater by Domenico Scarlatti, and Hindemith's Six chansons.

At Lacuna Arts, we feel that maintaining balanced voice parts is essential to quality choral singing. Placement into one of our performing groups is by audition only. Open auditions for new members are held in late August/early September and in January. Auditions at other times are by appointment only and on a space available basis. Rehearsals are Monday evenings in the Pacific Heights neighborhood of San Francisco. See the Rehearsal Schedule for dates, times, and locations of rehearsals and concerts.


We are pleased to announce our 2016 Summer Choral Workshops. These educational sessions offer an introduction to ensemble singing and are a great way to prepare to audition for one of our choirs or to get ahead on next season's repertoire. Thanks to the support of our donors, we are able to offer these workshops free of charge to the general public (advance registration required). Mondays, 7–9 pm at 2325 Union Street in San Francisco.

Solfège Bootcamp is a crash course in the fundamentals of music reading. If you can memorize the seven colors of the rainbow, you can learn the seven notes of the scale: Do, Re, Mi, Fa, Sol, La, and Ti. From its roots in medieval music theory to practical applications in the modern choral repertoire, this system of naming the notes will help you sing with more confidence and greater understanding.

Choral Reading Sessions will give you the opportunity to practice your music reading and ear training skills while exploring great works of choral literature. Learn to identify the particular challenges in any given work, and how to decide which reading techniques will be most appropriate.

Lacuna Arts Ensemble is our most selective amateur performing group, singing challenging a cappella choral music with as few as 1–3 voices per part. Participants in this tuition-free vocal chamber music program receive 2–3 additional group coachings with artistic director Sven Edward Olbash in preparation for each Chorale concert. They are also expected to put in additional practice and rehearsal time on their own. To audition for Ensemble, singers should generally have sung with Chorale for at least one season. Ensemble rehearsals are scheduled in advance according to singers' availability.
