While Wes Montgomery's legacy rests primarily on his revolutionary guitar technique and improvisational genius, his original compositions form an important part of the jazz repertoire. His writing, concentrated in the late 1950s and 1960s during his recordings for Pacific Jazz, Riverside, and Verve, produced several pieces that have become enduring standards. Four on Six, a driving sixteen-bar theme built on a relentless rhythmic motif, stands among the most frequently performed jazz guitar compositions. West Coast Blues introduced an unusual waltz-time feel to the blues form, while D-Natural Blues offered a more straightforward medium-tempo vehicle. Mr. Walker, also known as Renie, is an AABA tune reflecting his gift for memorable melody, and Movin' Along and So Do It! round out a body of original work that rewards both players and listeners. Montgomery composed with the improviser's ear, crafting themes that set up compelling harmonic pathways for soloing while remaining tuneful and accessible on their own terms. His brothers Buddy and Monk Montgomery, organist Melvin Rhyne, and producer Creed Taylor were among his closest musical associates. Montgomery's compositions, like his playing, continue to serve as foundational material for jazz guitarists worldwide.
