The shape of a piece: the sections and how they repeat.

What it is
Common structures: binary (AB), ternary (ABA), rondo (ABACA), theme and variations, strophic, twelve-bar blues, and verse–chorus with a bridge and a middle eight.
Where it applies
GCSE and A Level music.
How it works
Structure is what makes music followable — repetition creates familiarity, contrast creates interest, and the balance between them is the composer's decision.
How to use it in your work
Identify structure by listening for returns rather than by counting bars.
In composition, plan the structure first. Pieces that wander are the commonest weakness at GCSE, and a clear ABA gives you a shape to fill.
Where to get help
Your teacher and your board's assessment criteria — these subjects are marked against four or five stated objectives, and reading them is the single most useful hour you can spend.
