Funk is a rhythm-led 1970s genre that emerged from soul, R&B, and jazz in the late 1960s through James Brown, Sly & The Family Stone, and Parliament-Funkadelic. The defining elements are syncopated bass, tight horn sections, scratchy guitar, and the "one" — the heavily emphasised first beat of the bar. Funk underwrites virtually all subsequent dance and electronic music: disco took funk's rhythm to the dancefloor, hip-hop sampled it, house and techno preserved its kick-and-clap pulse. Tempos run 90–115 BPM. The form remains active through dedicated funk artists (Vulfpeck, Dam-Funk) and is the principal influence on contemporary nu disco and "boogie" production. Without funk, there is no modern dance music.
