The Voces Auream Chamber Choir is an initiative of Choral Conductor and Bass/Baritone Leon Griesbach based in Lisbon Falls, Maine focusing on Gregorian Chant and Renaissance Polyphony.

The purpose of this ensemble is to help others—singers and listeners alike—experience choral music that resonates at a deeply human level. An ensemble of focused singers pursuing a high level of excellence can achieve this vision, thereby becoming a source of inspiration for the broader community.


The many hours I have spent singing and conducting polyphony and chant have been some of the most meaningful in my life and I believe this is achieved by approaching Renaissance Polyphony and Gregorian Chant as living and exciting repertoire combined with animated interpretation, intense vocal mindfulness, and inspiring acoustics.

Beyond the overall mission for the ensemble, any choir can provide a great way to spend time with others while engaging in meaningful work! I joined a boy choir at the age of 7, and over the years choirs have given me friendships, an education, spiritual nourishment, laughter, tears, exhilaration, and a deep sense of fulfillment.

I would love to invite any interested singers to audition for this exciting new group!


Auditions are held in person by appointment in our rehearsal space (pictured above).

Due to the large amount of interest, auditions have been extended until February 9th.

The audition process:

  1. Interview. A chance for us to have an introduction, discuss the nature of the committment, and get to know one another.
  2. Vocalise: Two simple vocal exercises given to you at the time of the audition.
  3. Motet: Prepare and sing the Soprano, Alto, Tenor, or Bass line from Ave Verum Corpus by William Byrd (music here, but a score will be provided at the audition).
