Playing Wes Line and Django Line Over Fast 2-5s: Blues for Alice

What was the question?

Caro asked about applying the West Line and Django Line approach over fast 2-5 progressions — using Blues for Alice (which shares its first four bars with Confirmation) as the example. The question was about how to navigate the rapid chord motion using the FDA framework. That question comes in at (45:29).

The core idea (in plain English)

The first four bars of Blues for Alice contain a chain of fast 2-5s: F major 7, E minor 7 flat 5, A7, D minor 7, G diminished, D minor 7, G7, C minor 7, F7. The voice leading through all of those chords lives primarily on the second and third strings, moving chromatically downward toward the B-flat 7 in bar four. (45:29 — 47:17)

Charlie Parker's melody already contains that voice leading. What looks like a complex bebop melody on paper is, at its core, a guide tone line — the thirds of the chords, moving by half step from one chord to the next. This is not a coincidence. Parker wrote the melody from the harmony, and the harmony is moving by voice leading. (47:17 — 49:51)

The practical insight is this: you do not need to think about each 2-5 separately and assign a new line to each one. You follow the chromatic voice leading movement of the guide tones from chord to chord, and you stay on the West Line or Django Line based on chord function at each point in the sequence. The fast speed of the 2-5s does not change the underlying principle — it just means the half-step movements come more quickly. (53:05)

Fretboard breakdown (what to play)

  • Play the shell voicings of the first four bars of Blues for Alice without the root. Watch which note moves and by how much from one chord to the next. The voice movement is mostly by half step or whole step on the inner voices. (47:17)

  • In the key of F, the I chord (F major 6) has D minor as its upper structure — that is the West Line. Wes Montgomery consistently used his West Line in non-tonic functions within F-major contexts, and this is why: the G minor 2-5 function in F major pushes toward the West Line. (49:51)

  • The E minor 7 flat 5 to A7 is a 2-5 in D minor. The voice leading from that pair resolves to D minor, which is West Line. (51:20)

  • After the chromatic descent through the fast 2-5s, you hit B-flat 7 in bar four. From there, the second half of the tune has its own 2-5 sequence. The Django Line can mix with the West Line through that section — the function keeps alternating. (54:25 — 56:51)

  • An example of a complete line over this section — using the voice leading as the melodic thread — is demonstrated at (53:05). The line borrows from Donna Lee at the C minor 7 to F7 point, showing how bebop vocabulary and the FDA describe the same motion.

Common mistake to avoid

The common error on fast 2-5 sequences is treating each chord as a separate event requiring a distinct scale or arpeggio choice. The result is choppy playing that does not connect across bar lines. The guide tone movement is continuous — it moves smoothly from chord to chord because the voice leading is doing the work. Your job is to stay in the correct diagonal structure and let the guide tone lead the phrase forward. The individual chord changes become checkpoints, not starting points. (49:51)

A 10-minute practice assignment

Take only the first two bars of Blues for Alice: F major 7 moving to E minor 7 flat 5 to A7. Play the shell voicings without the root and name the voice that moves by half step at each change. Then try to connect those two chords with a single phrase — targeting the third of F major 7 first, then following the voice leading into E minor 7 flat 5 — using either the West Line or the Django Line structure, depending on chord function. Do not worry about the whole tune yet. Just make one smooth connection between those first two chords feel natural. (45:29 — 49:51)
