||Boléro is a one-movement orchestral piece by the Basque French composer Maurice Ravel. Originally composed as a ballet, the piece, which premiered in 1928, is considered Ravel's most famous musical composition. Boléro epitomizes Ravel's preoccupation with restyling and reinventing dance movements. It was also one of the last pieces he composed before illness forced him into retirement. Boléro is written for a large orchestra consisting of two flutes, piccolo, two oboes, cor anglais, E-flat clarinet, two B-flat clarinets, bass clarinet, two bassoons, contrabassoon, four horns, piccolo trumpet in D, three trumpets, three trombones, tube, three saxophones, timpani, two snare drums, cymbals, tam-tam, celesta, harp and strings. On April 8, 2008, the New York Times reported that Ravel may have been in the early stages of frontotemporal dementia in 1928, and that this condition might account for the repetitive nature of Boléro.
