Bridging the gap

In medieval music, a lacuna is a gap or missing section in a particular manuscript. Under the artistic direction of Sven Edward OlbashLacuna Arts bridges the gap between large community choirs and small professional choruses in the San Francisco Bay Area. We believe that the process of rehearsing serious music is fun, and that performing at a high level of excellence is its own reward.


lacuna 3This a cappella chorus  of  32–40 balanced voices is made up of singers from our Ensemble and Chamber Chorus. Repertoire for the 2014–2015 season includes Stanford’s monumental Magnificat in B-flat, Op. 164 and polychoral motets by Praetorius and G. Gabrieli. Placement into one of our performing groups is by audition only.

Our most selective group, Ensemble encourages individual responsibility with as few as 1–3 voices per part. Repertoire for the 2014–2015 season includes the Mass in G minor by Vaughan Williams, Palestrina’s Missa Hodie Christus natus est, Randall Thompson’s The Peaceable Kingdom, and D. Scarlatti’s exquisite 10-voice Stabat mater. Ensemble members may also choose to perform in the Chamber Chorus.

The 24-voice Chamber Chorus is for experienced and committed choral singers who enjoy performing challenging a cappella music in a fun, community setting. Repertoire for the 2014–2015 season includes the St. John Passion of Schütz, Parry’s Songs of Farewell, the Messe en style ancien by Langlais, and Renaissance motets by Eccard, Walter, and Hassler.

Rehearsals are either Monday or Wednesday evenings in the Pacific Heights neighborhood of San Francisco.


For those wanting to learn more about reading music, vocal technique, and performance practice, we offer a number of choral workshops throughout the year. Workshops do not require an audition and are open to the public. Participating in one of our workshops is a great way to supplement your choral singing experience or to prepare for an audition.
