African beliefs and practices are most certainly an influence in Cuba's music. Polyrhythmic percussion is an inherent part of African life & music, as melody is part of European music. Also, in African tradition, percussion is always joined to song and dance, and to a particular social setting. It is not simply entertainment added to life, it "is" life. The result of the meeting of European and African cultures is that most Cuban popular music is creolized. This creolization of Cuban life has been happening for a long time, and by the 20th century, elements of African belief, music and dance were well integrated into popular and folk forms.
