SynthesizerA synthesizer (also spelled synthesiser) 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. These sounds may be altered by components such as filters, which cut or boost frequencies; envelopes, which control articulation, or how notes begin and end; and low-frequency oscillators, which modulate parameters such as pitch, volume, or filter characteristics affecting timbre.
Electronic musical instrumentAn electronic musical instrument or electrophone is a musical instrument that produces sound using electronic circuitry. Such an instrument sounds by outputting an electrical, electronic or digital audio signal that ultimately is plugged into a power amplifier which drives a loudspeaker, creating the sound heard by the performer and listener. An electronic instrument might include a user interface for controlling its sound, often by adjusting the pitch, frequency, or duration of each note.
Sampler (musical instrument)A sampler is an electronic musical instrument that records and plays back samples (portions of sound recordings). Samples may comprise elements such as rhythm, melody, speech, sound effects or longer portions of music. The mid-20th century saw the introduction of keyboard instruments that played sounds recorded on tape, such as the Mellotron. As technology improved, cheaper standalone samplers with more memory emerged, such as the E-mu Emulator, Akai S950 and Akai MPC. Samples may be loaded or recorded by the user or by a manufacturer.
Synth-popSynth-pop (short for synthesizer pop; also called techno-pop) is a genre of new wave and pop music that first became prominent in the late 1970s and features the synthesizer as the dominant musical instrument. It was prefigured in the 1960s and early 1970s by the use of synthesizers in progressive rock, electronic, art rock, disco, and particularly the Krautrock of bands like Kraftwerk. It arose as a distinct genre in Japan and the United Kingdom in the post-punk era as part of the new wave movement of the late 1970s to the mid-1980s.
