Musicology and Musical Analysis

In 1966, Charles Keil introduced the term “engendered feeling” to capture a crucial aspect of jazz performance practice, that certain something beyond notation that performers add to music to make it “swing.” Engendered feeling subsumes the sense of rhythmic propulsion that Andre Hodeir once referred to as “vital drive,” the impulse that makes music come alive and induces listeners to movement. It stems, Keil insisted, not from syntactical processes that can be represented in common musical notation, but from musicians’ use of expressive microtiming at the sub-syntactical level in sustaining a rhythmic groove, a phenomenon he later dubbed “participatory discrepancies.” Research on expressive microtiming in jazz and other groove-based musics has largely followed suit and neglected the relevance of syntactical pattern for the production of engendered feeling. By contrast, I propose that engendered feeling arises from the systematic interaction of participatory discrepancies with aspects of syntactical pattern. Supplementing Christopher Hasty’s theory of metric projection with empirical research on expressive microtiming, I show how participatory discrepancies, operating at the sub-syntactical level, condition the way we experience rhythmic grooves at the syntactical level specifically through the operation of anacrusis at multiple levels of rhythmic structure, for it is the strategic manipulation of anacrusis that drives an effective groove. Analysis of the ride rhythm in jazz, the basic rock drumbeat, and the groove pattern of Herbie Hancock’s “Chameleon” illustrate how variations in timing serve either to enhance or attenuate the affective power of anacrusis, leading to subtle differences in engendered feeling.
