High-pitched flute (7)
I believe the answer is:
piccolo
'high-pitched flute' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for piccolo that I've seen before include "Part of 14 [ORCESTRA]" , "Small high-pitched flute" , "Instrument of the flute family" , "Little flute" , "producer of note" .)
