6 Little Eggs

Nightcore is an internet-born editing style that speeds up and pitch‑raises existing songs—typically by around a third in speed—so the vocals become brighter and more youthful and the groove turns more urgent. Practically, a classic nightcore edit accelerates a pop, Eurodance, or trance source by roughly 20–35% (the canonical meme is ~35%), which also lifts the pitch by about five and a half semitones—similar to playing a 33⅓‑rpm record at 45 rpm. The result is euphoric, hook‑forward, and highly kinetic, and it is often presented with anime or fan‑art visuals that emphasize its internet‑native identity.

Guaracha is a fast‑paced Cuban song–dance genre known for witty, satirical, and often picaresque lyrics delivered over a driving Afro‑Cuban groove. It typically uses the son clave (in 2–3 or 3–2 orientation), call‑and‑response coros, and a lively montuno section that invites dance and audience participation. Originally tied to popular and comic theater, guaracha later became a staple of Cuban conjuntos and charangas, and it survives in the salsa repertoire as a label for brisk, upbeat numbers. Instrumentation commonly includes voice(s), guitar or tres, bass, bongó, maracas, claves, and often trumpets or charanga flute/violins. Harmonies are straightforward and bright (major keys, I–IV–V with frequent secondary dominants), while the rhythmic feel is relentlessly syncopated and festive. The term should not be confused with modern "guaracha edm" (a separate, contemporary club style); historical Cuban guaracha is a distinct traditional genre with roots in 19th‑century Havana and theatrical culture.
