Drop (music)

The drop "...grew out of '70s rock". Since then, the TR-808 bass drop has been incorporated into a number of electronic dance music genres, either produced by a TR-808 or using a sample of a TR-808 bass drop. The EDM drop has continued to evolve over time, circulating through different sub-genres. == Genres ==

Electronic dance music Many genres of EDM have more than one drop during a track, especially if the song is built on a "dance-pop" verse/chorus with vocals; a drop may be heard somewhere during each chorus as the high point of that verse/chorus cycle. Some songs tend to emphasize a single drop as the beginning of the high point, or climax, of the track; in vocal sub-genres this occurs most in the last repetition of the chorus, while in nonvocal genres it occurs in the last quarter of the track. • In trap, the drop incorporates a dense vibration accompanied by a hard bass style. • In pop electronic music, the drop initiates a heavy bounce effect to be used for large audiences. Billboard magazine states that in 2016, the "pop-drop" is the "...post-chorus musical interlude that blends techniques from electronic dance music to hip-hop, and it's taken the chorus' place in pop music. • In dubstep, the drop involves a heavy full bass line and commonly a "wobble" or "vowel" bass accompanied by a strong shuffling beat. There can be emotional melodies combined with varies of common dubstep bass lines. Melodic dubstep is a sub-category under dubstep that includes powerful chords, with the use of different light melodies accompanied by the heavy bass line, to create harmonious melodies. • Electronic music DJs sometimes perform a "double drop": beatmatching two tracks where the drop, and hence the respective climaxes of both tracks, occur at the same time. Pop-drop Pop-drop is an element in a pop music track which, from a traditional perspective, serves as a kind of "post-chorus interlude", but is also regarded as the new climax point in pop music songs since the mid-2010s, downgrading the chorus to a building element of the drop section. It has been described as early as December 2016 by Switched on Pop author Charlie Harding in the Billboard magazine, claiming 2016 to be "the year of the pop-drop". In metalcore subgenres, bass drops are often utilized under the first chord of a breakdown, to emphasize the breakdown and give it a pronounced presence. A bass drop in this genre may be done using electronic drums with a sample pad triggered by the drummer or a backing track, either of which is sent to a venue's public address system. == Production ==

Tools and applications In EDM, drops are created on applications such as FL Studio, Ableton, or Logic. These are digital audio workstations built with electronic music-making capabilities that allow producers and DJs to fine-tune sounds for their music. Within these applications, producers can use built-in sound kits, custom sounds, or synthesizers to create unique electronic sounds and effects. Creation of the buildup and drop The composition of a drop is preceded by a buildup, which is accomplished through a transition from the verse into an interlude of repeating sounds, increased drum speed, and substantial volume growth. For example, in Calvin Harris's "This is What You Came For", the buildup consists of a repeating vocal line, accompanied by a rapidly increasing snare drum tempo, and swells of synthesizers rising in volume. The repetitive vocal lines and increase in volume and tempo create tension that is broken by the full capacity of the drop. Some build-ups end with a bar of silence that adds to the dramatic flair of the drop. The drop of a song may consist of a fuller bass, an affected vocal line, swelling atmospheric synthesizers, layered leads, hard-hitting drums, and white noise. The drop is the loudest portion of an EDM song. Buildup and verses are frequently utilized to bring focus to the drop. This is exemplified in "This is What You Came For", as the drop consists of a catchy vocal sample of the previous lyric "you" chopped up and heavily processed to create a repetitive and enchanting melody. This is complemented by a bass vox, layered house synths, and a high-hat focused drum beat. At the climax of the song, the drop in EDM diverges from the notions of pop songs that are vocal-heavy, and shifts it onto the electronic sounds. Live mixing Drop mixing is a transition technique which involves a sudden switch from one song to the next. There are two ways in which this can be done: "dropping on the one", where the transition occurs at the beginning of the bar, and "dropping at the four", where the transition occurs at the end of the bar. DJs use this technique at the location of the drop: the build-up of one song transitions into the break of another song. This abrupt change in melody or tempo can be used to draw the audience's attention to the performance. A similar drop technique commonly seen in trap and dubstep performances is drop swapping, where the build-ups of two songs are simultaneously played and then swapped at the climax. == Suggested physical effects ==

Effects on the brain The brain commonly interprets music through predictions and recognition of melodic patterns. This does not apply to a drop as it subverts musical predictability. For this reason, different regions of the brain can be stimulated more than others during a drop. According to one study during the pre-drop, the precentral gyrus and postcentral gyrus, whose functions are related to the recognition of tempo, pitch, rhythm and intensity, show the highest level of activity. Activation in this area correlates with the formation of emotions such as tension and anticipation. A large amount of activity in the PreCG and the PostCG during the pre-drop thus reflects the listener experiencing these emotions ahead of the climax. In an EDM drop, each component of the break routine creates a different intensity peak as they vary in structure and instrumentation. == References ==
