Nice production, but I can't support the ideas conveyed here. As far as I can see, it is just a super confusing shorthand for arbitrary details without offering any useful abstraction to really help you compose anything.

None of the songs in these examples were composed this way, and I just can't see what it really adds.

The "code" generates nothing, it's just a vague short hand description for sequenced blocks of midi data. It has no relation to "advanced music theory".

This will not help you to:

-write a chord progression

-melody over a chord progression

-Understand rhythm and syncopation in general (how to count it, how to compose with it)

-Understand what a motive actually is (the example used, like in Final Count Down, cut what most musicians would call the motive in half and calls them two separate motives)

-Teach you how to reason about music through actual code that a computer can execute.

-Teach you anything about music's mathematical properties, except for simply counting beats in a note pad.

The system doesn't even acknowledge the direction a pitch is moving when it acknowledges pitches at all.

Just learn traditional music theory. It will take you much further, and this is honestly tedious and complicated looking for offering no benefit comparatively. If you insist on remaining musically illiterate, just use your ears and rely on the grid in the software you are using to group beats for you visually. It's unnecessary to whip out the note pad and count the beats.
