Drumset and bass

Drum and bass

Drum and bass (commonly abbreviated to D&B, DnB, dnb, d'n'b, drum n bass, drum & bass, dNb, deebee, D+B, d+b, DNB, d and b, D and B), is a type of electronic dance music which emerged in the mid 1990s. The genre is characterized by fast breakbeatsbpm, occasional variation is noted in older compositions), with heavy sub-bass lines. Drum and bass began as an offshoot of the United Kingdom rave scene of the very early 1990s. Over the first decade of its existence, the incorporation of elements from various musical genres lent to many permutations in its overall style. (typically between 160–190 

History

In the late 1980s and early 1990s, a growing nightclub culture gave birth to a new electronic music style called Rave music, which combined regular beats alongside broken, syncopated beats, strong basslines and a faster tempo than that of house music. By 1991, musical tracks made up of only "broken" beats began to be known as "jungle", branching off into a separate musical genre (circa 1991-1992) popular at raves and on pirate radio in urban Britain.[citation needed]

These tracks often combined ragga vocal tracks with broken beats and bass lines. By 1994 jungle began to gain mainstream popularity and fans of the music (known as junglists) became a recognizable part of British youth subculture.[citation needed] After being further developed, the sound took on a very urban, raggamuffin sound, incorporating dancehall ragga-style MC chants, dub basslines, but also increasingly complex, high tempo rapid fire breakbeat percussion.[citation needed] At this time jungle began to be associated with criminals and criminal activity and perhaps as a reaction or perhaps independently of this, producers began to draw away from the ragga style and create what they labeled drum and bass.[citation needed] There is no clear point at which jungle became drum and bass, though most jungle producers continue to produce what they call drum and bass.[citation needed]

As the music style became more polished and sophisticated, it began to shift from pirate to commercial radio and gain widespread acceptance (circa 1995-1997). It also began to split into recognizable subgenres such as jump-up.[citation needed] As a lighter sound of drum and bass began to win over the musical mainstream, many producers continued to work on the other end of the spectrum. This resulted in a series of releases offering a dark, technical sound which drew more influence from techno music and the soundscapes of science fiction and anime films, this subgenre became known as techstep (circa 1997-1998).[citation needed]

Towards the turn of the millennium, the UK garage sound emerged and quickly eclipsed drum and bass in popularity. Drawing a key part of its inspiration from drum and bass, it was commonly believed that UK garage was a replacement of the genre and statements were made to the effect that "drum and bass is dead".[citation needed] However, consistent development of the genre proved otherwise. The appearance of the liquid funk and other subgenres brought a wave of new artists with new ideas and techniques, supporting continual evolution of the genre. Drum and bass is perhaps not well-known as a genre, but makes frequent, unrecognized appearances in the mainstream such as in television commercials, as well as being a major influence for other musical styles and some of its artists (notably Goldie).[1][citation needed]

[edit] Musicology of drum and bass

There are many views of what constitutes "real" drum and bass as it has many scenes and styles within it, from the highly electronic, industrial sounds of techstep through to the use of conventional, acoustic instrumentation that characterise the more jazz-influenced end of the spectrum. It has been compared with jazz where the listener can get very different sounding music all coming under the same music genre, because like jazz, it is more of an approach, or a tradition, than a style.[3] The sounds of drum and bass are extremely varied - and to a person unfamiliar to them, there may seem to be little connection between the subgenres. One common, though by no means universal, element is a prominent snare drum falling on the 2nd & 4th beats, with a less regular kick pattern around it.[citation needed]
Drum and bass could at one time be defined as a strictly electronic musical genre with the only 'live' element being the DJ's selection and mixing of records during a set. 'Live' drum and bass using electric, electronic and acoustic instruments played by musicians on stage has appeared and is a growing aspect of the genre.[4][5][6]
For the already mentioned reasons, the musicology of drum and bass is difficult to precisely define; however, the following key characteristics may be observed:

[edit] Importance of drum and bassline elements

The name "drum and bass" should not lead to the assumption that tracks are constructed solely from these elements. Nevertheless, they are by far the most critical features, and usually dominate the mix of a track. Despite the apparent simplicity of drum and bass productions to the untrained ear, an inordinate amount of time is spent on preparing tracks by the more experienced producers.[citation needed]
The genre places great importance on the "bass line", a deep sub-bass musical pattern which is felt physically as much as it is heard. There has also been considerable exploration of different timbres in the bass line region, particularly within techstep. Bass lines exist in many forms, but most notably they originate from sampled sources or synthesizers. Bass lines performed with a bass instrument, whether it is electric, acoustic or a double bass, are rare. An example of drum and bass played live with an electric bass can be found in the work of bands such as Squarepusher, Sonic Recreation, Sub Machena and STS9. Sampled basslines are often taken from double bass recordings or from publicly available loops. Synthesized bass lines are however just as common.[citation needed]
In drum and bass productions, the bass lines are subjected to many and varied sound effects, including standard techniques such as dynamic compression, flanger, chorus, over-drive, equalization, etc. and drum and bass specific techniques such as the "Reese Bass", a distinctive synthesized bass sound comprising layered 'clashing' sawtooth waves. Kevin Saunderson's 1988 classic "Just Another Chance" is widely recognised as the earliest example of the use of this technique.[citation needed]
Of equal importance is the "808" kick drum, an artificially pitch-downed or elongated bass drum sound sampled from Roland's classic TR-808 drum machine, and a sound which has been subject to an enormous amount of experimentation over the years.[7]
These bass techniques are fully appreciated in a club or rave environments where high quality woofers and powerful amplifiers are required to fully reproduce the eponymous basslines at high volume levels.[citation needed] This has led to the creation of very large and intensely loud touring soundsystems by producers wishing to show off their tracks, such as dubs from Soundman and dubs from Dillinja's Valve Sound System.[citation needed] This does not mean, however, that the music cannot be appreciated at home or accurately reproduced on personal equipment.[citation needed]
The complex syncopation of the drum tracks' breakbeat, is another facet of production on which producers spend a very large amount of time. A drum phrase lasting seconds may often take a day or more to prepare, depending on the dedication of the producer. The Amen break is generally acknowledged to have been the most-used (and often considered the most powerful) break in drum and bass.[8]
It would not be too much of an exaggeration to say that drum and bass (at least in its early days) was a style built around a single broken beat element which was a single sample, the Amen, but other samples have had a significant impact, including the Apache break, the Funky Drummer, and others.[9] The Funky Drummer has perhaps superseded the Amen in modern productions.
A commonly used break is the Tramen, a combined beat that is perhaps the ultimate statement on the fusion of musical styles in drum and bass as it combines the Amen, a James Brown funk breakbeat ("Tighten Up" or "Samurai" break) and an Alex Reece drum and bass breakbeat.[10]
The very fast (objectively) drum beat forms a canvas on which a producer can create tracks to appeal to almost any taste and often will form only a background to the other elements of the music. However, without a fast & broken beat, a drum and bass track would not be a drum and bass track but could be classified as a gabber, techno, breaks or house music track.[11]

[edit] Tempo

Drum and bass is usually between 160-180 BPM, in contrast to other forms of breakbeat such as nu skool breaks which maintain a slower pace at around 130-140 BPM. A general upward trend in tempo has been observed during the evolution of drum and bass. The earliest forms of drum and bass clocked in at around 130 bpm in 1990/1991, speeding up to around 155-165 BPM by 1993. Since around 1996, drum and bass tempos have predominantly stayed in the 173 to 180 range. Recently some producers have started to once again produce tracks with slower tempos (ie. in the 150s and 160s), but the mid-170 tempo is still the hallmark of the drum and bass sound.[12][13]
A track combining the same elements (broken beat, bass, production techniques) as a drum and bass track, but with a slower tempo (say 140 BPM), would not be drum and bass but a drum and bass-influenced breakbeat track.[14]
The speed of drum and bass is not however only characterised by that of the broken beat. Drum and bass has a bassline, which will typically play at half the speed of the drums, bringing its speed down to that of, for instance, a laid back hip-hop track.[citation needed] A listener or dancer can concentrate on this element rather than the faster drums.[citation needed]
An aggressively produced track with a complicated beat and synthesizer sounds may 'sound faster' than one with a sampled double bass bassline, guitar riffs and simpler beat, however the second track may be in strict BPM terms faster. Radio friendly tracks like Shy FX's "Shake Ur Body" often have higher BPMs than ominous techstep productions which might eject the uninitiated very quickly from a dancefloor.[citation needed]
The faster a track is in BPM terms, the less complex its drum patterns can be because at higher step the elements cease to be heard separately, turning them into a wall of sound. A faster drum and bass track will therefore generally have a less complex drum pattern than a slower one. These rules do not apply to a production from single drums (i.e., drum machines, sequencers, sliced beats.)[citation needed]
Live performances of drum and bass music on electric and acoustic instruments will often entail a drop in relative BPM (though not necessarily), unsurprising in light of the complexity of drum patterns and the high exertion required of a drummer.http://optimamusic.comcitation needed]
