At its core, dance music is built round rhythm. A steady beat offers the body something to comply with naturally. Whether or not it is house, techno, trance, drum and bass, disco, or EDM, the heartbeat of dance music typically matches the way folks move, breathe, and react. This rhythm creates momentum. It makes the listener tap a foot, nod their head, or dance without thinking too much about it. The energy comes from repetition, tempo, basslines, percussion, and gradual changes that keep the body engaged.
