Roland TR-808The Roland TR-808 Rhythm Composer, commonly known as the 808, is a drum machine manufactured by Roland Corporation between 1980 and 1983. It was one of the first drum machines to allow users to program rhythms instead of using preset patterns. Unlike its nearest competitor at the time, the more expensive Linn LM-1, the 808 generates sounds using analog synthesis rather than by playing samples. Launched when electronic music had yet to become mainstream, the 808 was a commercial failure.
Robert FrippRobert Fripp (born 16 May 1946) is an English musician, songwriter, record producer, and author, best known as the guitarist, founder and longest-lasting member of the progressive rock band King Crimson. He has worked extensively as a session musician and collaborator, notably with David Bowie, Blondie, Brian Eno, Peter Gabriel, Daryl Hall, Midge Ure, Talking Heads, and David Sylvian. He also composed the startup sound of Windows Vista operating system, in collaboration with Tucker Martine and Steve Ball.
ElectronicaElectronica is both a broad group of electronic-based music styles intended for listening rather than strictly for dancing and a music scene that started in the early 1990s in the United Kingdom. In the United States, the term is mostly used to refer to electronic music generally.
TechnodelicTechnodelic is the fifth studio album by Yellow Magic Orchestra, released in 1981. The album is notable for its experimental approach and heavy use of digital samplers which were not commonly used until the mid-to-late 1980s, resulting in a more minimalist and avant-garde sound compared to their previous work. It is considered the first released album to feature mostly samples and loops, influencing the heavy use of sampling and looping in popular music.
Microtonal musicMicrotonal music or microtonality is the use in music of microtones—intervals smaller than a semitone, also called "microintervals". It may also be extended to include any music using intervals not found in the customary Western tuning of twelve equal intervals per octave. In other words, a microtone may be thought of as a note that falls between the keys of a piano tuned in equal temperament. Microtonal music can refer to any music containing microtones.
VocoderA vocoder (ˈvoʊkoʊdər, a portmanteau of voice and encoder) is a category of speech coding that analyzes and synthesizes the human voice signal for audio data compression, multiplexing, voice encryption or voice transformation. The vocoder was invented in 1938 by Homer Dudley at Bell Labs as a means of synthesizing human speech. This work was developed into the channel vocoder which was used as a voice codec for telecommunications for speech coding to conserve bandwidth in transmission.
UnisonIn music, unison is two or more musical parts that sound either the same pitch or pitches separated by intervals of one or more octaves, usually at the same time. Rhythmic unison is another term for homorhythm. Two pitches that are the same or two that move as one. Unison or perfect unison (also called a prime, or perfect prime) may refer to the (pseudo-)interval formed by a tone and its duplication (in German, Unisono, Einklang, or Prime), for example C–C, as differentiated from the second, C–D, etc.
Envelope (music)In sound and music, an envelope describes how a sound changes over time. For example, a piano key, when struck and held, creates a near-immediate initial sound which gradually decreases in volume to zero. An envelope may relate to elements such as amplitude (volume), frequency (with the use of filters) or pitch. Envelope generators, which allow users to control the different stages of a sound, are common features of synthesizers, samplers, and other electronic musical instruments.
Grateful DeadThe Grateful Dead was an American rock band formed in 1965 in Palo Alto, California. The band is known for its eclectic style, which fused elements of rock, blues, jazz, folk, country, bluegrass, rock and roll, gospel, reggae, and world music with psychedelia; for its differentiated live performances centered around improvisation; and for its devoted fan base, known as "Deadheads". According to the musician and writer Lenny Kaye, "Their music touches on ground that most other groups don't even know exists.
Band-stop filterIn signal processing, a band-stop filter or band-rejection filter is a filter that passes most frequencies unaltered, but attenuates those in a specific range to very low levels. It is the opposite of a band-pass filter. A notch filter is a band-stop filter with a narrow stopband (high Q factor). Narrow notch filters (optical) are used in Raman spectroscopy, live sound reproduction (public address systems, or PA systems) and in instrument amplifiers (especially amplifiers or preamplifiers for acoustic instruments such as acoustic guitar, mandolin, bass instrument amplifier, etc.
