While reading the Puerto Rican article, I found a lot of information on Puerto Rico’s musical culture. The only thing I did not find was about the training, ritual, and apparel. Here is some information about these three cultural points that I found from reliable sources:
Training- taught from an early age to use complex rhythmic structures. Music incorporated into the elementary schools.
Rituals- most sites agreed that many of the rituals in the Santeria religion is incorporated into Puerto Rican music (specifically Salsa)
Apparel- depending on the band there can be specific apparel. Also, flowing dresses is important for many of the Puerto Rican dances.
