Recognizing common progressions (I-V-vi-IV, ii-V-I, etc.) by ear or analysis.
Why this node matters
One signal. More than one craft.
Practice in Songwriting can reinforce the same decision in Repertoire. The graph carries that evidence forward.

How a concept becomes useful
A concept is not a lesson to finish. It is a decision pattern the system can recognize in different kinds of work.
02 · Prove
Leave real evidence
A scored or completed exercise gives the graph something honest to carry forward.
03 · Transfer
Meet it elsewhere
The next plan can reinforce the same signal through another school or a deeper adjacent skill.
