From its inception, one of the defining characteristics of the electro sound was the use of
drum machines, particularly the
Roland TR-808, as the rhythmic basis of the track. As the genre evolved, computers and sampling replaced drum machines in electronic music, and are now used by the majority of electro producers. Although the electro of the 1980s and contemporary electro (
electronic dance music) both grew out of the dissolution of disco, they are now different genres. Classic (1980s) electro drum patterns tend to be electronic emulations of
breakbeats with a syncopated kick drum, and usually a snare or clap accenting the backbeat. The difference between electro drumbeats and breakbeats (or breaks) is that electro tends to be more mechanical, while breakbeats tend to have more of a human-like feel, like that of a live drummer. The definition however is somewhat ambiguous in nature due to the various uses of the term. The
Roland TR-808 drum machine was released in 1980, defining early electro with its immediately recognizable sound. Staccato, percussive drumbeats tended to dominate electro, almost exclusively provided by the TR-808. As an inexpensive way of producing a drum sound, the TR-808 caught on quickly with the producers of early electro because of the ability of its
bass drum to generate extreme low-frequencies. This aspect of the Roland TR-808 was especially appealing to producers who would test drive their tracks in nightclubs (like NYC's Funhouse), where the bass drum sound was essential for a record's success. Its unique percussion sounds like handclaps, open and closed high-hat, clave and cowbell became integral to the electro sound. A number of popular songs in the early 1980s employed the TR-808, including Marvin Gaye's “Sexual Healing,” Cybotron's “Clear,” and Afrika Bambaataa's “Planet Rock.” The Roland TR-808 has attained iconic status, eventually being used on more hits than any other drum machine. Through the use of samples, the Roland TR-808 remains popular in electro and other genres to the present day. Other electro instrumentation was generally electronic, favoring
analog synthesis, programmed bass lines, sequenced or arpeggiated synthetic riffs, and atonal sound effects all created with
synthesizers. Heavy use of effects such as
reverbs,
delays,
chorus or
phasers along with eerie synthetic ensemble strings or pad sounds emphasized the
science fiction or
futuristic themes of classic (1980s) electro, represented in the lyrics and/or music. Electro hip hop group
Warp 9's 1983 single,
Light Years Away, produced and written by
Lotti Golden and Richard Scher, exemplifies the
Sci-Fi,
afrofuturist aspect of electro, reflected in both the lyrics and instrumentation. The imagery of its lyrical refrain
space is the place for the human race pays homage to
Sun Ra's 1974
film of the same name, while its synth lines and sound effects are informed by sci-fi, computer games, and cartoons,"born of a science-fiction revival.". Although primarily instrumental, early electro utilized rap. Male rap dominated the genre, however female rappers are an integral part of the electro tradition, whether featured in a group as in
Warp 9 or as solo performers like
Roxanne Shante. The lyrical style that emerged along with electro became less popular by the 1990s, as rapping continued to evolve, becoming the domain of
hip hop music. About electro origins: ==History==
