Remarkable Parisian on piano, soaring (10)
I believe the answer is:
surprising
'remarkable' is the definition.
(thesaurus)
'parisian on piano soaring' is the wordplay.
'parisian on' becomes 'sur' ('on' in French).
'piano' becomes 'p'.
'soaring' becomes 'rising'.
'sur'+'p'+'rising'='SURPRISING'
(Other definitions for surprising that I've seen before include "Mildly astonishing" , "Causing astonishment" , "Unexpected" .)
