Supposedly, in this world, a quarter of an hour passes, in which Ravel’s “Bolero” does not sound somewhere. At least claims a fading at the end of the “Bolero” movie. A chewing gum is probably spat out every 0.0001 seconds somewhere in the world, but how do you want to prove something like that? We all agree that Maurice Ravel’s Bolero is one of the best known works of classical music. If he doesn’t even protrude into jazz. At least as far as the trombone is concerned, which can smear so nicely. And the cheeky dissonances shortly before the end. And of course the Bolero also anticipated the main attractions of electronic music: rhythm, repetition, ecstasy.
