I believe the answer is:

piccolo

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

'type of flute' is the definition.

I don't understand how the rest of the clue works.

(Other definitions for piccolo that I've seen before include "Instrument of the flute family" , "Small high-pitched flute" , "Instrument (meaning "little")" , "Little flute" , "producer of note" .)

I've seen this clue in The Times.
