frmusic1-6, Exercise 2: Interpreter and auteur-compositeur-interprete Model answer: An interpreter such as Piaf sings songs mostly written by others, and her way of singing makes them hers. An auteur-compositeur-interprete such as Brassens or Brel writes the words and the music and performs them. Both count as chanson because the tradition puts the voice, the words and the mood at the centre, and in it the interpreter can be as important as the author.
