Four on Six: The Octave Mastery of Wes Montgomery
Four on Six is one of the most famous and technically demanding jazz guitar standards, composed by the legendary Wes Montgomery. First recorded in 1960 for the album 'The Incredible Jazz Guitar of Wes Montgomery,' it is built on a series of rapid minor ii-V-i resolutions that move downward in whole steps.
Four on Six: Inside the Music
Every standard has a story, and Four on Six (in key of Gm) is a masterclass in songwriting and a foundational canvas for improvisation. Let's explore its unique approach to Minor ii-V sequences and octave-based melody..
A Musician's Perspective & Background
Wes Montgomery revolutionized jazz guitar with his thumb-driven technique and his masterful use of octaves, and Four on Six is the ultimate showcase of this style. Historically, it bridged the gap between hard-bop and the more modern, technically rigorous guitar styles that would follow.

Harmonic Deep-Dive
The harmonic hallmark of Four on Six is its use of sequential minor ii-V-i resolutions. The opening sections move from Gm7 to Cm7 - F7 to Bbmaj7, then Bbm7 - Eb7 to Abmaj7.
Gm7 (i)
Intervals: root, b3, 5, b7
Cm7 - F7 (ii-V of Bb)
Intervals: root, b3, 5, b7
Bbmaj7 (III)
Intervals: root, 3, 5, 7
Bbm7 - Eb7 (ii-V of Ab)
Intervals: root, b3, 5, b7
Melodic Ideas to Try
The melody is famously built on driving eighth-note runs and Wes’s signature octave technique. It has a 'sculpted' and percussive character that emphasizes the song's relentless forward motion.
The Groove & The Feel
Typically played at a fast swing tempo, Four on Six requires a rock-solid and driving rhythmic pocket. The rhythm section should focus on maintaining a clear, 'uncluttered' pulse that allows the guitar's intricate lines to be heard.
Improvisation Strategies
Soloing on Four on Six requires a high level of technical facility, especially if attempting Wes's octave or chord-melody styles. Focus on the sequential minor ii-V's and use Dorian and Melodic Minor scales to bridge the changes.
Summary & Takeaways
The primary takeaway is the mastery of sequential minor-key modulations and the development of high-speed technical facility. It teaches you how to maintain melodic focus across a rapidly shifting harmonic landscape.
