A jazz piece for "swinging".  It contains written-out parts with the cello and double bass alternating  in function between melody and accompaniment, written-out  improvisations along with accompaniment for both instruments, as well as  a section with chord-symbols for pure improvisations. This last section  may be skipped in case the performers do not think themselves capable  of improvising.
