Flex Dance Music (often abbreviated FDM) is a high-energy, battle-ready club sound created to accompany the Brooklyn street-dance style known as flexing. Built for showcases and one-on-one battles, the music emphasizes sudden drops, hollow spaces, and explosive percussive hits that mirror the dance’s bone-breaking, pausing, and gliding techniques. Rhythmically it draws heavily from dancehall while absorbing elements from East Coast club music, trap, and grime. Expect chopped vocal calls, airhorns, sirens, spin-backs, and subby 808s arranged in stark, stop–start patterns. Melodic content tends to be minimal and tense; the groove does the storytelling so dancers can punctuate the silence with dramatic movement.

Trap is a subgenre of hip hop that emerged from the Southern United States, defined by half-time grooves, ominous minor-key melodies, and the heavy use of 808 sub-bass. The style is characterized by rapid, syncopated hi-hat rolls, crisp rimshot/clap on the backbeat, and cinematic textures that convey tension and grit. Lyrically, it centers on street economies, survival, ambition, and introspection, with ad-libs used as percussive punctuation. Production is typically minimal but hard-hitting: layered 808s, sparse piano or bell motifs, dark pads, and occasional orchestral or choir samples. Vocals range from gravelly, staccato deliveries to melodic, Auto-Tuned flows, often using triplet cadences.
