Use of the term "techno" to refer to a type of electronic music originated in Germany in the early 1980s. Another distinguishing feature of techno music and techno aesthetic is the general embracement of creative use of music production technology. Techno tracks mainly progress over manipulation of timbral characteristics of synthesizer presets and, unlike other forms of EDM, that tend to be produced with synthesizer keyboards, techno does not always strictly adhere to the harmonic practice of Western music and such structures are often ignored in favor of timbral manipulation alone. Much of the instrumentation in techno emphasizes the role of rhythm over other musical parameters. Drum machines from the 1980s such as Roland's TR-808 and TR-909 are highly prized, and software emulations of such retro instruments are popular. Artists may use electronic instruments such as drum machines, sequencers, and synthesizers, as well as digital audio workstations. The central rhythm is typically in common time (4/4) and often characterized by a repetitive four on the floor beat. Techno is a genre of electronic dance music (EDM) which is generally produced for use in a continuous DJ set, with tempo often varying between 120 and 150 beats per minute (bpm).
