Guide Tones as Fretboard Stepping Stones in Jazz Guitar

Guide tones — the third and seventh of each chord — serve as stable landing points in jazz guitar improvisation, and mapping the diatonic notes that surround each guide tone is a productive way to expand vocabulary without losing harmonic clarity. This post explains what the Functional Diagonal Approach (FDA) requires before that mapping is reliable: the function of the chord must be identified first, because a minor chord functioning as the 2nd, 3rd, or 6th degree of the key will present a different set of surrounding diatonic notes even when the chord shape is identical.

Three-Finger Jazz Guitar Technique and Where Swing Feel Comes From

In jazz guitar, swing feel is generated by the physical movement of the left hand between notes — not by alternating pick direction on the right hand. This post explains the three-finger approach taught in the Functional Diagonal Approach (FDA), why the ring finger and pinky are treated as a single unit, what Wes Montgomery's right-hand technique actually shows, and why the common alternate-picking approach to swing produces a sound that does not swing.

How to Build Rhythmic Vocabulary for Jazz Guitar

How to Build Rhythmic Vocabulary for Jazz Guitar

Rhythmic vocabulary for jazz guitar is built by listening and singing long before it is built by playing — and it requires a personal musical identity to exist first, before transcription from other players can truly benefit you. This post explains the sequence Junewon Choi teaches in the Functional Diagonal Approach (FDA), including the practice method taught by his teacher Richard Hart, and why big band listening is one of the most direct paths to genuine swing feel.

Why Jazz Guitar Uses the 6th Degree on the One Chord

In bebop and swing jazz, the tonic I chord is almost always treated as a sixth chord, not a major seventh chord — a practice rooted directly in how Charlie Parker and the swing-era players heard and played the one. This post explains the historical and harmonic logic behind this choice, why George Benson's signature I-chord phrase is built around the 6th degree, and what it means for jazz guitar improvisation and the Functional Diagonal Approach (FDA).

How to Play Jazz Guitar Over Church and Pop Music

When a jazz guitarist plays over church or pop music — songs built on triads rather than seventh-chord harmony — the fastest and most reliable adaptation is the pentatonic block anchored to the melody. This post explains the approach Junewon Choi teaches in the Functional Diagonal Approach (FDA), including why melody must stay in your inner ear throughout the solo and how to listen like the masters who played it before you.

How to Adapt a Familiar Jazz Melody to Harmonic Minor Sound on Guitar

How to Adapt a Familiar Jazz Melody to Harmonic Minor Sound on Guitar

Adapting a familiar jazz melody to harmonic minor sound requires identifying specific scale degrees and substituting them with their harmonic minor equivalents — replacing the major sixth with a flat sixth and the major third with a minor third. This post explains the one-to-one note mapping method Junewon Choi described at the April 4 VLJG Office Hour.

Sparse Jazz Guitar Comping With Shell Voicings: How to Comp Yourself

Sparse Jazz Guitar Comping With Shell Voicings: How to Comp Yourself

Creating rhythmically engaging sparse jazz guitar comping requires stripping chords down to their guide tones — the third and seventh of each chord — using shell voicings as the source material. This post explains how shell voicings generate both solo lines and sparse accompaniment, and how to build the sound Junewon Choi demonstrated at the April 4 VLJG Office Hour.

Tonic vs. Non-Tonic in the FDA: Getting the Chord Function Right

Tonic vs. Non-Tonic in the FDA: Getting the Chord Function Right

Knowing whether a chord is tonic or non-tonic in the FDA determines which diagonal line you use — and getting that wrong means the whole system breaks down. This post clarifies the G minor 7 and E-flat major 7 relationship in the key of B-flat and explains how to apply tonic and non-tonic assignments consistently around the circle of fifths.

Secondary Dominants and Upper Structure Chords Inside the FDA

Secondary Dominants and Upper Structure Chords Inside the FDA

Secondary dominants follow a specific rule — circle-of-fifths motion resolving to a diatonic chord — and within the FDA, their upper structure chords are simply West Line or Django Line structures sitting a half step above the resolution point. This post explains how every secondary dominant fits into the same binary framework you already know.
