A discussion of the role of music in Spike Lee's cinema, examining the function of music as atmospheric, iconic, and moral conscience. In particular, I am interested in how jazz forms the atmospheric or ambient sound in his work, reminding us of Bleek's drunken defense of jazz as African American affect, tradition, and mood in Mo' Better Blues. As well, I am interested in how Lee uses key songs by Stevie Wonder and related figures to indicate the moral frame of a given film, an entry ramp into the meaning of the film an d composed of sound embedded in Black cultural life.
