“Salsa dancing 
  applies to Latin music that became popular in the United States during the 1970s. 
  It contains Latin rhythms from jazz and disco. The salsa was originally the 
  name of a certain type of music rather than the name of a specific dance. The 
  group of dances that evolved from the 1970s are loosely labeled ‘salsa’ 
  by contemporary dancers.” (Lydia Martinez, 2002)
