The melody is like an intricate collage. If you take it on all at once, you hear one song, one whole sound. But if you listen for the viola and cello, the flute and clarinet, you hear how each note lies next to the other to complete an image, how the French horn and tuba complements them all. How the piano and xylophone, the cymbals and drums hold them up like a base color. How the picture wouldn’t be the same without each note in its just-right place.
