Sharp crooked instruments (5)
I believe the answer is:
harps
'instruments' is the definition.
(harp is a kind of instrument)
'sharp crooked' is the wordplay.
'crooked' indicates anagramming the letters (a crooked or disrupted version of the letters).
'sharp' is an anagram of 'HARPS'.
(Other definitions for harps that I've seen before include "Musical instruments of sharp kind" , "Dwells" .)
