21.38Reharmonization and melody tension

Suppose melody is G.

Chord E7 contains:

E G♯ B D.

G natural is not a basic chord tone.

But over E7, G can function as:

♯9

That may be great in blues/jazz.

So “does not belong to chord” does not automatically mean “wrong.”

The question is:

Is this tension stylistically and functionally convincing?
