The bolero's origins are in Cuba. It started around the 19th century and blossomed from a Cuban popular song as a style of its own.

Boleros are also popular in Spain but they are radically different than the Latin-American counterpart. In the Spanish version, the couples dances apart, while in the Latin-American, the couples embraced.  The Spanish version is written in 3/4 time while the Latin American version is in 2/4 time. African based rhythms at the very base of the Latin-American bolero. 

Maurice Ravel (1875-1937). French, son to a Swiss father and Spanish Mother, Ravel combined skill in orchestration with meticulous technical command of harmonic resources. He wrote in an attractive musical idiom that was entirely his own, in spite of contemporary comparisons with Debussy, a composer his senior by some twenty years. A deeply impressionistic style filled with the deepest romanticism.

The Bolero is one of the best known works on the planet and unique in every way...recognizable after only a few bars. 

Ravel died of a brain tumor and some recent investigations by a British doctor indicate that he suffered from Alzheimer disease because  "...the famous melody repeated 18 times without change during the course of the piece demonstrates that the French composer was possibly succumbing to Alzheimer's disease. Perseveration, an obsession with repeating words and gestures, is one of the more notable symptoms of this pathology"... Now, with all due respect, with that type of approach, we have to assert that Pachelbel's Canon is a Mental institution case, not to mention most music with variations... 

The Music was introduced massively by Blake Edwards in the 1979 Warner comedy "10" (Dudley Moore, Bo Derek). The guitar transcription I propose is irresistible... It is an applause magnet and it is very impressive... The technical challenges are well defined and I consider the piece a must in the contemporary guitarist repertoire.
