Ambient

Ambient music is a musical genre that focuses largely on the timbral characteristics of sounds, often organized or performed to evoke an "atmospheric", "visual" or "unobtrusive" quality. Ambient evolved from the early 20th century music of the impressionists, composers such as John Cage, Morton Feldman and minimalist composers and early electronic composers of the 1960s and 1970s, to rock musician Brian Eno, who is responsible for coining the phrase ambient music in the manifesto liner notes of his 1979 album Ambient 1: Music for Airports. Ambient music has influenced many other genres, most remarkably some forms of rhythmic music presented in chill-out rooms at raves and other dance events, with the intention of creating a calmer, relaxed atmosphere for ravers to take a break from dancing.- Wikipedia

Downtempo-Chill

Downtempo (or Downbeat) is a laid-back electronic music style similar to ambient music, but usually with a beat or groove unlike the beatless forms of Ambient music. The beat is sometimes made from loops that have a hypnotic feeling. Sometimes the beats are more complicated and more featured instead of being in the background, but even then they are usually less intense than other kinds of electronic music like Trance. Often the name chill out music is used to refer to songs demonstrative of the genre, but those names also refer to other styles of music, and downtempo encompasses a wider variety of styles than those terms alone would indicate. Another related genre is trip hop, though downtempo usually uses a slower tempo than trip hop. Due to the relaxing and often sensual or romantic feel of most downtempo music, along with the absence or minimal use of lyrics or vocals, it is a popular form of background music in 'chill out rooms' of dance parties, and many alternative cafes. -"Wikipedia"

Dub

Dub is a form of music, evolved from reggae in the early 1970s, that involves revisions of existing songs[1]. The dub sound consists predominantly of instrumental remixes of existing recordings and is achieved by significantly manipulating and reshaping the recordings, usually by removing the vocals from an existing music piece, emphasizing the drum and bass frequencies or 'riddim', adding extensive echo and reverb effects, panoramic LR delay, and dubbing occasional snippets of lyrics from the original version.  A very close cousin of the Trip-Hop and Illbient genres, Electro Dub is another open-ended downtempo style designed for after-hours consumption. The things that classify Electro Dub is the Dub-inspired use of lo-fi programming, heavy delay, and deep reggae elements, all of which act as chilled seasonings in a more modern, electronic production.-"Wikipedia"

Drum-N-Bass

Drum and Bass (commonly abbreviated to DnB, dnb, drum n bass and drum & bass) is a type of electronic dance music also known as jungle. Emerging in the early 1990s, the genre is characterised by fast tempo broken beat drums (generally between 160 & 180 beats per minute) with heavy, often intricate basslines. Today, drum and bass is still considered an underground musical style, but its currents of influence run throughout popular music and culture. Drum and bass began as an offshoot of the United Kingdom breakbeat hardcore and rave scene of the late 1980s; and over the first decade of its existence there have been many permutations in its style, incorporating elements from ragga, dancehall, electro, funk, hip hop, house, jazz, heavy metal, reggae, rock, techno and trance. -"Wikipedia"

House

House music is a style of electronic dance music that was developed by dance club DJs in Chicago in the early to mid-1980s. House music is strongly influenced by elements of the late 1970s soul- and funk-infused dance music style of disco. House music takes disco's use of a prominent bass drum on every beat and developed a new style by mixing in a heavy electronic synthesizer bassline, electronic drums, electronic effects, funk and pop samples, and reverb- or delay-enhanced vocals.  - -"Wikipedia"

Lounge

Lounge music is a retrospective description of music popular in the 1950s and 1960s encompassing the exotica, easy listening, and space age pop genres. It is a type of mood music meant to evoke in the listeners the feeling of being in a place — a jungle, an island paradise, outer space, et cetera — other than where they are listening to it. ^[1] The range of lounge music encompasses beautiful music-influenced instrumentals, modern electronica (with chillout, Nu-jazz and downtempo influences), while remaining thematically focused on its retro-space-age cultural elements. The earliest type lounge music appeared during the 1920s and 1930s, and was known as Light music. -"Wikipedia"

Nu-Jazz

Nu jazz is an umbrella term coined in the late 1990s to refer to music that blends jazz elements with other musical styles, such as funk, electronic dance music, and free improvisation[1]. Also written nü-jazz or NuJazz, it is sometimes called electronic jazz, electro-jazz, e-jazz, jazztronica, jazz house, phusion, or future jazz. Historically, jazz music has incorporated electronic instruments in production even as early as Miles Davis and Herbie Hancock. In the early 90s, jazz music began to embrace production of music with electronic instruments, thereby fusing together a traditional and modern sound, and thus emerging Nu Jazz onto the electronic music scene. The sound of Nu Jazz can be described as jazz music with a slow tempo from about 65-100 B.P.M. generally alongside an ambient beat, and usually little to no vocals are involved. Nu Jazz music rhythms and melodies can often be repetitive in nature. Nu Jazz can also be referred to as Jazz Fusion or Electro-Jazz. -"Wikipedia"

Trip-hop

Trip-hop is a music genre also known as the Bristol sound. The trip-hop description was applied to the musical trend in the mid-1990s of downtempo electronic music that grew out of England's hip hop and house scenes. It is often rejected as a term by those artists to whom it is applied. It has also been described as "Europe's alternative of choice in the second half of the '90s", and a one-up fusion "of Hip-Hop and Electronica until neither genre is recognizable." ^[1] It is thus categorized as a fairly experimental genre, and sometimes with elements of Dance.
