Techno ac

Techno is a genre of electronic music which is generally produced for use in a continuous DJ set, with tempos being in the range from 120 to 150 beats per minute (bpm). The central rhythm is typically in common time and often characterized by a repetitive four on the floor beat. Artists may use electronic instruments such as drum machines, sequencers, and synthesizers, as well as digital audio workstations. Drum machines from the 1980s such as Roland's Roland TR-808 and Roland TR-909 are highly prized, and software emulations of such retro instruments are popular in this style.
