64.82This is an important conceptual convergence

We are no longer learning isolated tricks.

We are seeing one pitch environment through different lenses:

Scale lens

seven-note collection.

Pentatonic lens

five-note concentrated color.

Triad-pair lens

two three-note shapes.

Quartal lens

stacked-fourth fragments.

Upper-structure lens

familiar shape over bass/shell.

You choose the lens that makes the musical task easiest.
