About Resonance


Resonance is a 30-voice ensemble based in San Luis Obispo, California, under the direction of Paul Osborne. Founded in 2012, Resonance performs a variety of a cappella choral repertoire, with emphases on Renaissance polyphony, contemporary compositions, and music of the Midwest Choral tradition as pioneered by the St. Olaf Choir. Other influences include The Concordia Choir, The Tallis Scholars, The King’s Singers, and the Voices of Ascension.


Resonance exists to preserve the tradition of a cappella singing by selecting challenging and stimulating repertoire to be performed by skilled vocalists. We aim to bring the community and our members together by connecting the past and the future through the universal language of music.
