A synthesizer (also synthesiser [1] or synth) is an electronic musical instrument that generates audio signals. Synthesizers typically create sounds by generating waveforms through methods including subtractive synthesis , additive synthesis and frequency modulation synthesis .
Examples of electromechanical sound producing devices include the telharmonium, Hammond organ, electric piano, and the electric guitar. Purely electronic sound production can be achieved using devices such as the theremin , sound synthesizer , and computer . [ 2 ]
Synth-pop (short for synthesizer pop; [10] also called techno-pop [11] [12]) is a music genre that first became prominent in the late 1970s and features the synthesizer as the dominant musical instrument. [13]
Synthwave is a microgenre [9] [10] of electronic music [1] that draws predominantly from 1980s films, video games, and cartoons, [11] as well as composers such as John Carpenter, Jean-Michel Jarre, Vangelis, and Tangerine Dream. [12] [13] Other reference points include electronic dance music genres including house, synth, and nu-disco. [14]
Electronic synthesizers quickly become a standard part of the popular-music repertoire. The first movie to use music made with a (Moog) synthesizer was the James Bond film On Her Majesty's Secret Service in 1969. After the release of the film, composers produced a large number of movie soundtracks that featured synthesizers.
A digital synthesizer is a synthesizer that uses digital signal processing (DSP) techniques to make musical sounds, in contrast to older analog synthesizers, which produce music using analog electronics, and samplers, which play back digital recordings of acoustic, electric, or electronic instruments. Some digital synthesizers emulate analog ...
A musical instrument synthesizer synthesizes the sound of specific instruments from generic hardware. Of course, a significant difference in these concepts is that musical instrument synthesizers typically only generate musical sound, whereas a synthetic instrument in test and measurement may be equally likely to generate or to measure some ...
Another possible disadvantage is that not all of the variable performance parameters available on a synthesizer can be actuated from a guitar; a synth guitar lacks assignable controls to open a filter in real-time, for example. Nevertheless, contemporary synth-guitar designs often include an expression pedal for such purposes.
