Strategy sees piano being encircled by exotic instrument (4,4)
I believe the answer is:
game plan
'strategy' is the definition.
(game plan is a kind of strategy)
'piano being encircled by exotic instrument' is the wordplay.
'piano' becomes 'p' (musical abbreviation).
'being encircled by' means one lot of letters goes inside another.
'exotic instrument' becomes 'gamelan' (I've seen this before. I am not sure about the 'exotic' bit.).
'p' going within 'gamelan' is 'GAME PLAN'.
'sees' acts as a link.
Can you help me to learn more?
(Other definitions for game plan that I've seen before include "Strategy planned in advance" , "Strategy (in match)" , "business strategy" , "Carefully thought-out strategy for achieving an objective" , "'Strategy worked out in advance (4,4)'" .)
