Mosa Tsay is a contemporary-minded cellist and concert experience designer based in San Francisco and New York City.

Mosa performs with Wavefield Ensemble in NYC and has been a frequent collaborator with International Contemporary Ensemble (ICE) for the premiere of multimedia opera “Echo Drift” at PROTOTYPE Festival and Anna Thorvaldsdottir’s album, AEQUA. She has collaborated with over 30 composers in her work with AXIOM, New Juilliard Ensemble, and Eco Ensemble. Mosa is an alumna of Doublestop Foundation and performed as an ambassador of the foundation after winning its Instrument Loan Competition in 2014. She was featured as a soloist (Schelomo and Schumann Cello Concerto) with the UC Berkeley Symphony Orchestra, as winner of its Concerto Competition. Other notable performances include the 2017 Juilliard and Sibelius Academy tour to Stockholm and Helsinki with Esa-Pekka Salonen, and Mendelssohn octet with Danish String Quartet.


As former Artistic Director of Celli@Berkeley and a San Francisco-based collective of cellists, Mosa commissioned and premiered new works for celli and electronics in the San Francisco Bay Area. In 2014, she co-produced Celli@Berkeley’s debut CD album in collaboration with composer Jared Redmond and Grammy-winning Barry Phillips. 


Mosa recently received her Master of Music from The Juilliard School. She holds bachelor's degrees in Music and in Society and Environment from UC Berkeley. Her honors thesis explored “Silence: In Performance and Within the Performer,” an analysis of the role of silence in music by J.S. Bach, Hans Werner Henze and John Cage. 


Born to Taiwanese parents, she began playing cello at age seven in San Diego. Her past teachers include Joel Krosnick, Jonathan Koh, and Catherine Godden.
