Of Music and Mourning, commissioned and premiered by Daniel J. Cosio, is a five-movement cycle for based on the Kübler-Ross five stages of grief. The five movements were composed by five CU Boulder student composers, each corresponding to one stage of grief: denial, anger, bargaining, depression, and acceptance. Each movement is written for a different member of the trombone family (soprano, alto, tenor, bass, and contrabass). The fifth and final movement, Acceptance, was written by Blake for contrabass trombone and piano.
