Why Power Chords Can Feel 'Boring' in Jazz
What was the question?
David observed that moving power chords (root and fifth) alongside guide tones offers a "neutral" way to ride through chord changes. He asked for thoughts on using this neutrality versus the functional harmony typically taught in jazz.

The core idea (in plain English)
Power chords are indeed neutral because they lack the third and the seventh—the notes that define the quality (major/minor) and function (dominant/tonic) of a chord. While rock music relies on this ambiguity, jazz relies on "storytelling" through tension and release. If everything is neutral, there is no conflict and no resolution. To tell a story, you need to commit to a sound (happy, sad, tense, resolved), which requires the third and seventh.

Fretboard breakdown (what to play)
Analyze the Pentatonic/Power Chord: Notice that a standard pentatonic scale or power chord often omits the tritone intervals that define the key's function. (10:39)
The Problem with Neutrality: Without the 3rd or 7th, there is no "leading tone." There is no note demanding to move to the next chord.
Injection of Function: To speak the language of jazz, shift your focus from the Root/5th shapes to the 3rd/7th intervals. This provides the "balance" needed to say something meaningful rather than staying safe. (13:10)

Common mistake to avoid
Avoid relying on "safe" notes all the time. While playing neutral pentatonics or power chords guarantees you won't hit a "wrong" note, it also guarantees you won't play a "right" note that defines the harmony. Don't be afraid to make a statement with the color tones.
A 10-minute practice assignment
Play a backing track of a standard you know well.
For one pass, play only root and fifth (power chords) or major pentatonic. Notice how safe but static it feels.
For the next pass, play only the 3rds and 7ths of every chord.
Compare how the second pass forces the "story" of the harmony to move forward.
