Musica tropical or tropical music (Spanish: Música tropical) is a broad term for vocal and instrumental music with "tropical" flavor usually associated with caribbean music. It is part of an even broader category of latin music. Usually it is an upbeat dance music, but also includes ballads. It features complex, syncopated rhythms and draws from traditional music forms. Its sound is based on traditional percussion and string musical instruments, such as timbales, congas, bongo, the tres, but can also incorporate other instruments and advanced machinery, such as synthesizers and drum machines.
