This is the most open-ended workshop so far. You now know how chords function in a key — which ones feel like home, which ones create tension, and how they resolve. That's enough to write a complete piece with both a chord progression and a melody.

The exercises here work in two stages: first you'll build a progression (with some constraints on which chords to use and how to end it), then you'll write a melody on top of it. The melody should come from what you know — chord tones, stepwise motion between them, a stable starting and ending point.

Think of this as a sketch, not a finished song. Four to eight measures. A shape, a direction, a moment of tension and release. That's all you're going for.
