Formal structure in dance music
In motion art, the cycle is accomplished through narrative or dramatic structure. This cycle of tension and release forms the basis of all great films, books, computer games, and music. Many dance music records will employ a low-pass or high-pass filter, removing a significant amount of energy from the frequency range and slowly open the filter to build up energy and anticipation in the listener. In electronic dance music that is destined for radio, this commonly involves the lead motif but lacking in full presence or missing the complete drum section or bass. Energy in music is associated with both pitch and frequency. If the pitch of a melody rises or the frequency content of the track or timbre is increased, then we determine this as an increase in the overall energy of the music. When the music reaches the drop, the most commonly applied effect is the low-pass filter.
