Bomba is an Afro‑Puerto Rican drum‑dance tradition that emerged among enslaved Africans and their descendants on the island’s coastal plantations and port towns. It centers on a vibrant dialogue between a solo dancer’s improvised moves and a lead drum that answers each gesture in real time, supported by a steady ensemble groove, call‑and‑response singing, and communal chorus. The core ensemble uses barrel drums (barriles) made from rum barrels: a buleador (or segundo) that maintains the ostinato and a subidor/primo that improvises to the dancer. Musicians also play cuás (wooden sticks on the drum’s shell) and a single maraca, typically held by the lead singer. Bomba includes several regional rhythms—such as sicá, yubá, cuembé, and holandés—each with its own tempo, swing, and dance vocabulary. Beyond entertainment, bomba has functioned as a vehicle for resistance, social commentary, and community identity, and today it thrives in both Puerto Rico and its diasporas, often fusing with jazz, salsa, and contemporary popular styles.

Jazz is an improvisation-centered music tradition that emerged from African American communities in the early 20th century. It blends blues feeling, ragtime syncopation, European harmonic practice, and brass band instrumentation into a flexible, conversational art. Defining features include swing rhythm (a triplet-based pulse), call-and-response phrasing, blue notes, and extended harmonies built on 7ths, 9ths, 11ths, and 13ths. Jazz is as much a way of making music—spontaneous interaction, variation, and personal sound—as it is a set of forms and tunes. Across its history, jazz has continually hybridized, from New Orleans ensembles and big-band swing to bebop, cool and hard bop, modal and free jazz, fusion, and contemporary cross-genre experiments. Its influence permeates global popular and art music.

Alternative is an umbrella term for non-mainstream popular music that grew out of independent and college-radio scenes. It emphasizes artistic autonomy, eclectic influences, and a willingness to subvert commercial formulas. Sonically, alternative often blends the raw immediacy of punk with the mood and texture of post-punk and new wave, adding elements from folk, noise, garage, and experimental rock. While guitars, bass, and drums are typical, production ranges from lo-fi to stadium-ready, and lyrics tend toward introspection, social critique, or surreal storytelling. Over time, “alternative” became both a cultural stance and a market category, spawning numerous substyles (alternative rock, alternative hip hop, alternative pop, etc.) and moving from underground circuits to mainstream prominence in the 1990s.
