Original: Maurice Ravel used a pentatonic scale as the basis for a melody in "Passacaille", the third movement of his Piano Trio, and as a pastiche of Chinese music in "Laideronette, Emperatrice des Pagodes", a movement from his Ma Mère l'Oye (Mother Goose).
Simplified: Maurice Ravel used it to write music which sounded Chinese, and in his Mother Goose suite (Ma Mère l'Oye) which sounds like a fairy tale.
