This Alberto Lattuada’s movie was one of 16 scored by Ennio Morricone during that year. “Preludio d’Amore” is an attractive piece romantic, but with a definite nod to the musical trends of the day. The pick of the themes is “Amore per Amore”, a ravishing creation with an outstanding solo flute part. It’s such a beautiful theme, one for the list of Morricone pieces which the whole world would know had it been written for a more famous film.
