The Wikipedia describes "son montuno" music, thusly: "The son montuno is a subgenre of son cubano. The son itself is the most important genre of Cuban popular music. In addition, it is perhaps the most flexible of all
forms of Latin-American music, and is the foundation of many Cuban-based dance forms, and salsa. Its great strength is its fusion between European and African musical traditions
There are many types of son of which the son montuno is one. The term has been used in several ways. Probably the 'montuno' originally referred to its origin in the mountainous regions of eastern Cuba; eventually it was used more to describe the final up-tempo section of a son, with its semi-improvisation, repetitive vocal refrain and brash instrumental climax.
The term was being used in the 1920s, when son sextetos set up in Havana and competed strongly with the older danzones."
Okay, class is over :-)
