Latin jazz is a fusion of jazz harmony and improvisation with Afro–Latin American rhythms, song forms, and percussion. It combines the swing, bebop, and big-band traditions with clave-based grooves such as son, rumba, danzón, and mambo, and later integrates Brazilian feels like samba and bossa nova. Typical features include the use of the clave (2–3 or 3–2), piano montunos (guajeos), bass tumbao patterns, timbales cáscara, conga marcha, and call-and-response horn "mambo" figures. While the rhythm section locks into cyclical patterns, soloists improvise using the vocabulary of jazz, creating music that is both danceable and harmonically rich.

Polca criolla is the Peruvian creole adaptation of the European polka, rendered in the coastal "música criolla" idiom of Lima and other coastal cities. It is typically lively and festive, set in 2/4 meter with a buoyant, accentuated "oom-pah" feel, and performed with the signature coastal ensemble of guitars, cajón, handclaps (palmas), and often the quijada (donkey jawbone), with bright, agile vocals. While formally rooted in salon dance traditions of the 19th century, polca criolla bears the rhythmic drive, street-party humor (picardía), and call-and-response performance style of Peruvian jaranas (house parties), making it a staple alongside vals criollo, marinera, and festejo in the broader criollo repertoire.
