Music producer in shot: “Cut!” (7)
I believe the answer is:
piccolo
'music producer' is the definition.
'piccolo' can be an answer for 'producer' (I have seen 'producer of note' mean 'piccolo' so perhaps 'producer' could also mean 'piccolo'). I'm not certain of the 'music' bit.
'shot cut' is the wordplay.
'shot' becomes 'pic' (I've seen this in another clue).
'cut' becomes 'colo' (I am not sure about this - if you are sure you should believe this answer much more).
'pic'+'colo'='PICCOLO'
'in' is the link.
Can you help me to learn more?
(Other definitions for piccolo that I've seen before include "Musical instrument - little (Italian)" , "Small high-pitched flute" , "High flute" , "Instrument of the flute family" , "Part of 14 [ORCESTRA]" .)
