Boléro

Boléro has no movements, only one long unbroken arc. It opens almost inaudibly: a snare drum taps out a steady rhythm that will repeat, unchanged, for the entire piece. Over it, a flute introduces a long, snaking melody in two halves, each played twice before the next instrument takes over. That is the entire plan: the same melody, the same rhythm, passed from instrument to instrument, family to family, getting louder and denser each time. Listen for the melody's odd, off-balance shape, it never quite resolves where you expect. Track the parade of solo colors, clarinet, bassoon in an unusually high register, saxophones, trumpet, oboe d'amore, each giving the tune a different personality. Gradually strings and full brass join in, the harmony thickens, and the volume climbs from a whisper to a roar. There is no pause anywhere, no change of tempo, just one long inevitable buildup. The payoff comes in the final minute: the music suddenly wrenches into a different harmony, a jolt after fifteen minutes of sameness, before the whole orchestra slams down on a final, abrupt cadence. First-time listeners should simply track the crescendo and enjoy guessing which instrument gets the tune next.

Ravel composed Boléro in 1928 on commission from the dancer Ida Rubinstein, who wanted a piece for a ballet with a Spanish setting, a woman dancing on a tabletop in a tavern as onlookers gradually join in. Ravel reportedly said he wanted to write a piece built entirely on orchestral tone color, with no real development, just one theme repeated over an unchanging rhythm. The ballet premiered at the Paris Opera in November 1928 and was well received, but the concert version quickly eclipsed the staged one and became Ravel's most famous work worldwide, far surpassing anything else he wrote in popularity. Ravel himself was reportedly surprised by its success, considering it a minor experiment rather than a major composition. It has since become a fixture of orchestral programming and has been used widely in film, television, and figure skating.
