“FROM BLUES TO LATIN JUST IN TIME: A rhythmic analysis of ‘Unit Seven’”

Abstract

Just in Time (Lopes 2003) is an empirically devised rhythmic analytic model which assesses the operation and qualities of rhythm and metre, and their interaction with other parameters. This paper will investigate the operation of the durational parameters in the jazz standard ‘Unit Seven’ by Sam Jones, as performed by the Wes Montgomery Quartet (Verve 823-448-2, 1984). This piece was chosen for two basic reasons. First, its position as mainstream jazz allows an assessment of the rhythmic operation in a highly kinetic genre. Second, it includes a section in binary metre which provides different metric contexts in the same piece, therefore broadening the spectrum of the analysis. The consistent use of particular rhythmic constructions supports the arguments concerning the importance of the durational parameters in the kinetic quality and structural definition of a piece, while the assessment of the ongoing dialogue between pitch and durational parameters demonstrates the importance of the durational structure of music.
