Techno is a genre of electronic dance 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. The central rhythm is typically in common time (4/4) 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. Use of the term Techno to refer to a type of electronic music originated in Germany in the early 1980s. This tee design is an homage to a certain gaming company.
