Delicacy used to finish piece, a complex composition (5)

I believe the answer is:

fugue

I'm a little stuck... Click here to teach me more about this clue!

'composition' is the definition.
(I know that fugue is a type of composition)

I can't explain the rest of the clue.

(Other definitions for fugue that I've seen before include "Yearly records" , "A musical form; a memory loss" , "One musical form ..." , "Composition involving a repeated interwoven melody" , "Musical form paired with toccata" .)

I've seen this clue in the Sydney Morning Herald.
