Bloco is the umbrella term for Brazilian street parade ensembles that animate Carnival and year‑round festivities with powerful percussion, communal singing, and dancing.
A bloco typically gathers a large bateria (drum corps) and a crowd of revelers who follow a moving sound source—sometimes purely acoustic, sometimes with amplified vocals, guitars, and brass. Repertoires blend classic carnival marchinhas, samba in its many variants, frevo, afoxê/ijexá grooves, axé hits, and contemporary pop or rock reworked into carnival rhythms. Call‑and‑response vocals, catchy refrains, and shouted cues (“paradinhas” and “convenções”) shape the energy of the parade.
Unlike competitive samba schools confined to the Sambadrome, blocos occupy public streets and squares, emphasizing spontaneity, inclusivity, and neighborhood identity. Regional branches add strong local colors: Rio’s samba and marchinha tradition; Recife/Olinda’s frevo brass and massed crowds; Salvador’s blocos afro and trio elétrico culture with axé and samba‑reggae. The result is a participatory, high‑intensity carnival sound and social experience.
Street Carnival in Brazil coalesced into organized neighborhood groups in the early 1900s. In Rio de Janeiro, the older cordões and ranchos evolved into blocos carnavalescos, led by singers (puxadores) and massed percussion (bateria). Their core repertoire drew on newly popular samba and the sing‑along marchinha—defining sounds of Rio’s street Carnival.
From the 1990s, street Carnival boomed across Brazilian cities. New blocos embraced eclectic repertoires—rock, pop, funk, and international covers rearranged for bateria and brass—while maintaining carnival structures (paradinhas, convenções, refrains). Community workshops professionalized percussion teaching; hundreds of blocos now parade in Rio, São Paulo, Belo Horizonte, Recife/Olinda, and beyond.
Diaspora communities and visiting musicians imported the bloco model worldwide. International groups emulate Brazilian bateria setups, teaching sambista technique and staging parades that translate the bloco’s participatory, high‑energy ethos into local contexts.
Choose a rhythmic base consistent with your regional flavor:
•Samba batucada (Rio): ~100–140 BPM, with surdo patterns (1 on the downbeat; 2 and 3 syncopating), caixa telecoteco, tamborim carreteiro.
•Frevo (Recife/Olinda): brisk 160–200 BPM with driving snare figures and agile brass syncopations.
•Afoxê/Ijexá (Salvador): ~90–110 BPM, cyclical bell (agogô) timelines and conga/timbau dialogues; for samba‑reggae, accent strong backbeats and layered surdo voicings.
•Arrange paradinhas (sudden breaks) and convenções (set hits) to cue crowd responses and dynamic peaks.
