Overwhelmed by Extensions? Let the Melody Decide
What was the question?
Sebastian noted that you can build triads off various extensions (the 3rd, 5th, 7th, 9th, etc.). He expressed feeling overwhelmed by the options: "How do you decide when to build off the 3rd versus the 5th or 7th? Is there a rule?" (48:30)
The core idea (in plain English)
The decision is rarely up to you; it is up to the Melody. The melody dictates the harmony. You cannot simply choose a fancy extension if it clashes with the melody note of the song (51:14).
When we play jazz standards, we are respecting an existing composition. The "Musician is the architect" concept applies when you compose, but when you play a standard, the melody is your boss. If you want to use a specific upper structure or tension, you must check: does this support the melody, and does it voice-lead correctly to the next chord?
Fretboard breakdown (what to play)
Check the Top Note: Look at the melody note for the bar you are playing.
Harmonize Down: Build your chord so the melody is the top note.
Example (E7): If the melody is F# (the 9th), you can't play an altered chord with a Flat 9 (F natural) just because you "feel like it." It will clash.
Kenny Burrell approach: Use open strings or drop voicings to let the melody breathe on top while the harmony supports it from below (53:05).
Common mistake to avoid
A major mistake is treating "licks" or "fancy chords" as universal keys that open every door. Students often learn a concept (like "build a triad off the 9th") and try to force it onto every chord in a tune. This destroys the song. Always analyze the melody first.
A 10-minute practice assignment
Take a standard you know. Go through the melody and identify the interval of the melody note relative to the bass. Is it the 3rd? The 5th? The #11? Pick one chord where the melody is a tension (like a 9th or 13th) and build a voicing specifically to support that note, rather than using a stock grip.
