Boom bap is a foundational East Coast hip hop style defined by hard, punchy drums—“boom” for the kick and “bap” for the snare—laid under sample-based loops from jazz, soul, and funk records. It typically runs around 85–96 BPM, favors gritty, minimally processed textures (often associated with SP‑1200 and early Akai MPC samplers), and foregrounds lyrical skill: multisyllabic rhyme schemes, internal rhymes, storytelling, street reportage, and battle bars. DJ techniques such as scratching and cut‑choruses are common, and arrangements emphasize head‑nod grooves, sparse basslines, and tight bar structures that give MCs room to “sit in the pocket.”

Hip hop is a cultural and musical movement that emerged from Black, Latino, and Caribbean communities, centering around rapping (MCing), DJing/turntablism, sampling-based production, and rhythmic speech over beats. It prioritizes groove, wordplay, and storytelling, often reflecting the social realities of urban life. Musically, hip hop is built on drum-centric rhythms (from breakbeats to 808 patterns), looped samples, and bass-forward mixes. Lyrically, it ranges from party anthems and braggadocio to political commentary and intricate poetic forms, with flow, cadence, and rhyme density as core expressive tools. Beyond music, hip hop encompasses a broader culture, historically intertwined with graffiti, b-boying/b-girling (breakdance), fashion, and street entrepreneurship, making it both an art form and a global social language.

Lo-fi is a music aesthetic and genre defined by an embrace of audible imperfections—tape hiss, clipping, room noise, distorted transients, and uneven performance—that would be treated as errors in high-fidelity recording. Emerging from the DIY ethos of American indie and punk scenes, lo-fi turns budget constraints and home-recording limitations into a signature sound. Songs are often intimate, direct, and unvarnished, prioritizing immediacy and personality over polish. Typical lo-fi recordings use 4-track cassette or similarly modest setups, simple chord progressions, and understated vocals, spanning rock, folk, pop, and experimental approaches while retaining a homemade warmth and nostalgic patina.

West Coast rap is a regional style of hip hop that emerged in California in the early to mid‑1980s and came to worldwide prominence in the 1990s. Sonically, it leans on funk and R&B—especially 1970s P‑Funk—with elastic, melodic basslines, glossy synth leads, talkbox/vocoder hooks, and laid‑back but hard‑hitting drum programming. Rhythms typically sit around 85–100 BPM with a relaxed, behind‑the‑beat flow, crisp claps on 2 and 4, and deep, sustained 808 kicks. Lyrically, it ranges from street reportage and social commentary to cruising anthems and party records, often steeped in West Coast slang and car culture (lowriders, freeway cruising). The style encompasses Los Angeles/Compton/Long Beach as well as Bay Area aesthetics, later flowering into sub‑movements like G‑funk, hyphy, jerkin’, and ratchet.

Underground rap is hip‑hop created and distributed outside the commercial mainstream, prioritizing lyrical depth, experimental production, and DIY ethics over radio formats and chart ambitions. It typically features dense wordplay, multisyllabic and internal rhyme schemes, social critique, and introspective storytelling over gritty sample-based beats. Production often embraces lo-fi aesthetics—dusty drums, chopped jazz/soul/psych samples, and minimal hooks—while releases are commonly self-financed, issued via indie labels, or shared directly with fans. Culturally, underground rap is a networked movement of ciphers, open mics, college radio, indie record shops, message boards, and Bandcamp scenes that values authenticity, craft, and community.
