The moment when the full beat and bass return after a buildup — the climactic release the buildup has been pointing toward.
Definition
The drop is the moment of climactic release in a trance arrangement — when, after the breakdown and buildup have suspended the listener in tension, the kick drum, bassline, and main synth elements return at full strength. In uplifting trance the drop traditionally re-introduces the rolling 16th-note bassline and a soaring lead synth playing the track's main hook. In progressive trance and melodic techno the drop may be more subtle, with the rhythm returning before the melody fully reasserts itself. The drop is where dancefloors react most visibly — hands rise, energy peaks — and producers spend enormous craft on making each drop a satisfying payoff for the buildup that preceded it.
