Synth rock

The use of electronic music technology in rock music coincided with the practical availability of electronic musical instruments and the genre's emergence as a distinct style. Rock music has been highly dependent on technological developments, particularly the invention and refinement of the synthesizer, the development of the MIDI digital format and computer technology.

In the late 1960s, rock musicians began to use electronic instruments, like the theremin and Mellotron, to supplement and define their sound; by the end of the decade the Moog synthesizer took a leading place in the sound of emerging progressive rock bands who would dominate rock in the early 1970s. In the 1980s, more commercially oriented synthpop dominated electronic rock. In the new millennium the spread of recording software led to the development of new distinct genres including electroclash, dance-punk and new rave.

Experiments in tape manipulation or musique concrète, early computer music and early sampling and sound manipulation technologies paved the way for both manipulating and creating new sounds through technology. The world's first computer to play music was CSIRAC in 1950-1, designed and built by Trevor Pearcey and Maston Beard and programmed by mathematician Geoff Hill. Early electronic instruments included the theremin, which uses two metal antennas that sense the position of a player's hands and control oscillators for frequency with one hand, and amplitude (volume) to produce an eerie but difficult to manipulate sound. It was used by avant garde and classical musicians in the early twentieth century and was used on a large number of 1940s and 50s science fiction films and suspense.
