Composer finally takes a bow (5)
I believe the answer is:
satie
'composer' is the definition.
(French composer Erik Satie)
'finally takes a bow' is the wordplay.
'finally' indicates one should take the final letters.
'bow' becomes 'tie' (I've seen this in another clue).
The final letter of 'takes' is 's'.
's'+'a'+'tie'='SATIE'
(Other definitions for satie that I've seen before include "French composer (Trois Gymnopedies)" , "French avant-garde composer, Erik, d. 1925" , "Erik -, nineteenth to twentieth century French composer" , "creative Frenchman" , "French composer of the Gymnopedies, d. 1925" .)
