The Tucson Symphony Orchestra Chorus is a volunteer ensemble under the direction of Dr. Marcela Molina.

The Tucson Symphony Orchestra Chorus was founded by Bruce Chamberlain in 2003. Since then, the Chorus has given critically acclaimed performances of Handel’s Messiah, Beethoven’s Symphony No. 9 and Missa Solemnis, Mozart and Brahm’s Requiems, Bernstein’s Symphony No. 3, “Kaddish” and Orff’s Carmina Burana.

The Chorus returned to the stage in the 2022-23 season with two interim co-directors, Drs. Marcela Molina and Ben Hansen, and performed the much-anticipated Beethoven’s Ninth and Mahler’s “Resurrection,” as well as Handel’s Messiah and holiday selections.

The Chorus performs annually with the TSO on multiple performances, ranging from small to large scale. For the 2023-24 Season, the Chorus will perform Messiah, Verdi’s Requiem and Holst’s Planets.


Audition for the 23-24 chorus!

Please email the TSO Chorus to schedule an audition. Rehearsals will be held Monday evenings starting after Labor Day weekend.
