Epic want solo pared down on one instrument (7)
I believe the answer is:
pianola
'one instrument' is the definition.
(Pianola is an example)
'epic want solo pared down' is the wordplay.
'epic want solo' becomes 'piano' (I am not sure about this - if you are sure you should believe this answer much more).
'pared' says to take the centre (pare or remove edges from the word).
'down' becomes 'blah' (I've seen this in another clue).
The middle of 'blah' is 'la'.
'piano'+'la'='PIANOLA'
'on' is the link.
Can you help me to learn more?
(Other definitions for pianola that I've seen before include "Melody Maker" , "A bridge hand easy to play" , "Mechanical piano" , "Automatic instrument" , "Mechanical keyboard instrument" .)
