The Chamber Music Society of Colombo (CMSC) was conceptualized in 1998 by a few musicians living in Sri Lanka.

The Ensemble of the CMSC made its debut in January 2007 with a concert for the Sri Lankan President, Mahinda Rajapaksa.

[3] Works commissioned in this manner have led to three world premieres being performed by the ensemble: "Beyond the Horizon" by Premasiri Khemadasa, and "Paths in the Forest" and "Dawn of Kandula", both by Stephen Allen.

In March 2012, a collaboration with the Goethe Institute in Colombo began with an ongoing series entitled "Chamber Music Plus".

[5] The 2009-2010 season was mostly dedicated to presenting concerts and workshops celebrating the significant birth and death anniversaries of Henry Purcell, George Frideric Handel, Joseph Haydn, and Felix Mendelssohn.
