Trance is a genre of electronic music that developed during the 1990s in Germany. It is characterized by a tempo lying between 125 and 150 beats per minute (BPM), repeating melodic phrases, and a musical form that distinctly builds tension and elements throughout a track often culminating in 1 to 2 "peaks" or "drops." Although trance is a genre of its own, it liberally incorporates influences from other electronic music styles such as techno, house, pop, chill-out classical music, tech house, ambient, and film music.
A trance refers to a state of hypnotism and heightened consciousness. This is portrayed in trance music by the mixing of layers with distinctly foreshadowed build-up and release. A characteristic of virtually all trance music is a mid-song climax followed by a soft breakdown disposing of beats and percussion entirely, and leaving the melody and/or atmospherics to stand alone for an extended period before gradually building up again. As a result, trance tracks are often lengthy to allow for this progression and have sufficiently sparse opening and closing sections to facilitate mixing by DJs.
Trance can be purely instrumental, although vocals are also a common feature. Typically they are performed by mezzo-soprano to soprano female soloists, often without verse/chorus structure. Structured vocal form in trance music forms the basis of the vocal trance subgenre, which has been described as "grand, soaring, and operatic" and "ethereal female leads floating amongst the synths".
Trance as a word in music has been used for a very long time. The first usage of Trance close to the origin of Trance as a music genre is the British act The KLF on their 1988 track "What Time Is Love (Pure Trance 1)", on which the record sleeve is also annotated "Pure Trance". This track however cannot be classified as Trance but it is (Techno) Rave as it clearly lacks the features of Trance. The very first Trance record (also British) is "Age Of Chance – Time's Up (Remix)"  and dates from 1989 soon followed by "Age Of Love" (1990). The remix by Jam & Spoon of that track speeded up the genre. Dance 2 Trance is also an early example of trance music, having first released single in 1991.
Other schools of thought argue the name may refer to an induced emotional feeling, high, euphoria, chills, or uplifting rush that listeners claim to experience, while other suggestions trace the name to the actual trance-like state the earliest forms of this music attempted to emulate in the 1990s before the genre's focus changed.
Some trace Trance's antecedents back to Klaus Schulze, a German experimental electronic music artist who concentrated in mixing minimalist music repetitive rhythms and arpeggiated sounds (specifically his 1988 album "En=Trance". In truth it was really Sven Väth, his labels and others in the same group that saw the initial releases of trance Another possible antecedent is Yuzo Koshiro and Motohiro Kawashima's electronic soundtracks for the Streets of Rage series of video games from 1991 to 1994, and the Wangan Midnight Maximum Tune series. It was promoted by the well-known UK club-night megatripolis (London, Heaven, Thursdays) whose scene catapulted it to international fame.
Examples of early Trance releases include but are not limited to German duo Jam & Spoon's 1992 12" Single remix of the 1990 song The Age Of Love., German duo Dance 2 Trance's 1990 track "We Came in Peace".
One writer traces the roots of trance to Paul van Dyk's 1993 remix of Humate's "Love Stimulation". However, van Dyk's trance origins can be traced further back to his work with Visions Of Shiva, which were his first ever tracks to be released. In subsequent years, one genre, vocal trance, arose as the combination of progressive elements and pop music, and the development of another subgenre, epic trance, had some of its origins in classical music., with film music also being influential.
Classic trance employs a 4/4 time signature, a tempo of 125 to 150 BPM, and 32 beat phrases and is somewhat faster than house music. A kick drum is usually placed on every downbeat and a regular open hi-hat is often placed on the upbeat or every 1/8th division of the bar. Extra percussive elements are usually added, and major transitions, builds or climaxes are often foreshadowed by lengthy "snare rolls"—a quick succession of snare drum hits that build in velocity, frequency, and volume towards the end of a measure or phrase.
Rapid arpeggios and minor keys are common features of Trance, the latter being almost universal. Trance tracks often use one central "hook", or melody, which runs through almost the entire song, repeating at intervals anywhere between 2 beats and 32 bars, in addition to harmonies and motifs in different timbres from the central melody. Instruments are added or removed every 4, 8, 16, or 32 bars.
In the section before the breakdown, the lead motif is often introduced in a sliced up and simplified form, to give the audience a "taste" of what they will hear after the breakdown. Then later, the final climax is usually "a culmination of the first part of the track mixed with the main melodic reprise".
As is the case with many dance music tracks, trance tracks are usually built with sparser intros ("mix-ins") and outros ("mix-outs") in order to enable DJs to blend them together immediately. As trance is more melodic and harmonic than other electronic dance music, the construction of trance tracks in the proper way is particularly important in order to avoid dissonant (or "key clashing," i.e., out of tune with one another) mixes.
More recent forms of trance music incorporate other styles and elements of electronic music such as electro and progressive house into its production. It emphasizes harsher basslines and drum beats which decrease the importance of offbeats and focus primarily on a four on the floor stylistic house drum pattern. The bpm of more recent styles tends to be on par with house music at 120 - 135 beats per minute. However, unlike house music, recent forms of trance stay true to their melodic breakdowns and longer transitions.
Trance music is broken into a large number of subgenres. Chronologically, the major subgenres are classic trance, acid trance, progressive trance, uplifting trance, and hard trance. Uplifting trance is also known as "anthem trance", "epic trance", "stadium trance", or "euphoric trance", and has been strongly influenced by classical music in the 1990s and 2000s by leading artists such as Ferry Corsten, Armin Van Buuren, Tiesto, Push, Rank 1 and at present with the development of the subgenre "orchestral uplifting trance" or "uplifting trance with symphonic orchestra" by such artists as Andy Blueman, Soundlift, Arctic Moon, Sergey Nevone&Simon O'Shine etc. Closely related to Uplifting Trance is Euro-trance, which has become a general term for a wide variety of highly commercialized European dance music. Several subgenres are crossovers with other major genres of electronic music. For instance, Tech trance is a mixture of trance and techno, and Vocal trance "combines [trance's] progressive elements with pop music". Balearic beat, which is associated with the laid back vacation lifestyle of Ibiza, Spain, is often called "Balearic trance", as espoused by Roger Shah. The dream trance genre originated in the mid-1990s, with its popularity then led by Robert Miles. There is also a slower bpm trance music, this styles are often called "psybient" (synonyms are "psychill", "ambient trance").
Since the 00's, trance music is often divided into Uplifting Trance and Progressive Trance so as to appeal to a wider pop music generation, the latter in particular is more 'electro-pop' than trance and has become the baby of most online former trance shows and DJs. Thus, many well-known compilations such as A State Of Trance usually showcase Progressive Trance in disc 1 and Uplifting in disc 2. Labels once associated with only Uplifting Trance have also been known to set up more progressive-oriented imprints, for example, Enhanced Music, Alter Ego Recordings, Infrasonic Recordings and Anjunadeep. As opposed to Uplifting Trance, Progressive Trance, which is now usually presented simply as 'progressive' given its departure from its trance roots, features a slower bpm, predominantly remaining around 130 - 140, higher emphasis of grooving bass lines rather than kicks. The tempo has a rule to be higher in Progressive Trance than in Progressive House, since it can be very similar to each other. A common thought-process for trance artists delineating from traditional "uplifting trance" structures and foundations is that the slower bpm allows for more interesting groove creation. Prominent labels releasing Progressive Trance are Armind, Lost Language and Anjunabeats.
