"Gloria’s Step" and Paul Motion (132) 

Scott LaFaro's "Gloria's Step" is one of the defining compositions of modern jazz and a lasting testament to his brilliance as both a bassist and composer. Introduced on the landmark 1961 album Sunday at the Village Vanguard, the tune departs from conventional jazz forms through its asymmetrical 20-bar structure, shifting major-seventh harmonies, and absence of a clearly defined key center. These qualities create a floating, conversational framework that mirrors the trio's remarkable interplay. Drummer Paul Motian was essential to the performance's success. Rather than marking time conventionally, Motian painted the music with subtle brushwork, shifting textures, and elastic rhythms that allowed Bill Evans and LaFaro complete freedom. His sensitive, interactive approach helped redefine the role of the jazz drummer, making the trio an ensemble of equal voices rather than a piano-led group. Together, LaFaro's innovative composition and Motian's understated artistry helped create one of the most influential recordings in jazz history.
