Bolero was composed by Maurice Ravel in 1928 as a ballet score, built around a single melody repeated over and over while the orchestra gradually grows louder. That hypnotic repetition and slow crescendo made it one of the most recognisable pieces of classical music, frequently used in films, adverts and concert programmes to suggest mounting tension or ceremony. Short excerpts now circulate online because the theme is instantly familiar even to people who do not know its title, and this Jurandy rendition preserves that steady, building quality in a compact clip ideal for reuse.
