Serene is a short, lyrical post-bop instrumental by Eric Dolphy, originally released in 1960 on the Prestige album Out There. Dolphy plays bass clarinet, with Ron Carter on cello, George Duvivier on bass, and Roy Haynes on drums. The tune is in Eb major, in 4/4 time with a swinging blues-inflected feel, and runs about 1 minute 54 seconds. It unfolds across three choruses, delivering a calm, introspective solo that gives the piece its serene mood. The track is a typical example of Dolphy’s early post-bop explorations, featuring a slow swing and a distinctive bass-clarinet voice.
