Join the Chamber Orchestra for Improvisionaries: a season -long exploration of the art of improvisation. The Chamber Orchestra , in partnership with the Philadelphia Clef Club of Jazz, will celebrate this landmark season with a variety of programs exploring the art of improvisation spanning the 17 th through 21 st centuries. It will illuminate the immensely varied and colorful musical trajectory which supplied an essential framework to the birth of jazz, as well as the myriad links between jazz and classical music. The season will culminate with the premiere of a new work by COP’s Steven R. Gerber Composer-in Residence, Adam Vidiksis featuring players from the Clef Club.
