A song feels like it's going somewhere when each part changes something from the one before it: one more instrument, one fewer, a busier beat, a new sound.
- First verse: sparse — the voice and one or two instruments.
- First chorus: fuller, but not everything yet.
- Second verse: a little fuller than the first.
- Second chorus: one new layer — a harmony, strings, a shaker.
- Bridge: drop down, or go somewhere new.
- Last chorus: the biggest moment of the song.
- Outro: wind down, or stop on purpose.
