52.96This prepares us for larger song arrangements

When we reach those two pieces you asked to master in multiple variations, we'll need both sides:

Workshop 50 principle

same melody, changing world.

Workshop 52 principle

same riff/phrase, escalating delivery.

Together they allow you to turn a straightforward popular song into a full piano performance with:

intro

multiple choruses

style changes

solo

breakdown

shout section

and ending—

without losing the tune.
