Laboratorio is a Brazilian micro‑scene within contemporary hip hop that coalesced around artist‑run collectives and label ecosystems (most visibly Laboratório Fantasma). It blends boom‑bap and modern trap sensibilities with MPB, samba, and neo‑soul harmony, placing lyricism and social commentary at the core. The sound is defined by sample‑friendly, groove‑rich beats, live percussion drawn from Afro‑Brazilian traditions, and melodic hooks that often nod to MPB and samba‑soul. Artists use Portuguese lyricism to address race, class, identity, and everyday life, pairing incisive bars with warm, humanized production and frequent collaborations across rap, R&B, and pop.

Contrabass (double bass) as a classical genre centers on music written to feature the lowest member of the violin family as a solo and chamber instrument, as well as concertante works with orchestra. Emerging at the end of the Classical era and flowering in the Romantic period, the repertoire ranges from elegant Viennese concertos with distinctive historical tunings to virtuosic 19th‑century showpieces and 20th/21st‑century modernist and post-tonal works. The idiom exploits the instrument’s cavernous resonance, lyrical cantabile in the upper register, and a wide coloristic palette (arco, pizzicato, harmonics, sul ponticello/​tasto). Hallmarks include cantabile melodies supported by orchestral or piano textures, idiomatic passagework using positions and harmonics, and cadenzas that highlight the instrument’s surprising agility and expressive range.
