63.48Level 15 — another dominant upper structure
G7 altered.
LH: B-F.
RH: A♭ major:
A♭ C E♭.
Over G:
♭9
11
♭13.
But C conflicts with B if held densely.
You might instead use:
E♭ major triad over G7:
E♭ G B♭ includes root G though.
Or use specific altered shapes.
The point:
upper structures must be chosen by sound and voice-leading, not from a memorized chart blindly.
