The piano I played for an African (9)
I believe the answer is:
ethiopian
'an african' is the definition.
(Ethiopian is an example)
'the piano i played' is the wordplay.
'played' indicates anagramming the letters.
'the'+'piano'+'i'='thepianoi'
'thepianoi' anagrammed gives 'ETHIOPIAN'.
'for' acts as a link.
(Other definitions for ethiopian that I've seen before include "from African country" , "African national" , "Like Emperor Haile Selassie?" , "Citizen of north-east African state" , "found in Addis Ababa" .)
