Strange job an instrumentalist may hold (5)
I believe the answer is:
banjo
'instrumentalist may hold' is the definition.
I can't judge whether this defines the answer.
'strange job an' is the wordplay.
'strange' indicates anagramming the letters.
'job'+'an'='joban'
'joban' with letters rearranged gives 'BANJO'.
Can you help me to learn more?
(Other definitions for banjo that I've seen before include "Formby's instrument" , "Relative of the guitar" , "Something instrumental" , "strumming instrument" , "Instrument with long neck and round body" .)
