Triple Albums - Manual Sequence and Automatic Sequence

Manual Sequence and Automatic Sequence

With regard to records, most double album sets have sides 1 and 2 back to back on the first disc, followed by sides 3 and 4 on the second disc, etc. The record industry term for this practice is "manual sequence." However, some double album LP sets have sides 1 and 4 pressed on one disc along with sides 2 and 3 on the other. This practice, known as "automatic sequence," began in the early 1960s and was intended to make it easier for listeners to play through the entire set in order on automatic record changers. The use of automatic sequence gradually declined during the 1970s as automatic record changers fell out of favor. High quality manual turntables became more affordable and are often preferred because they cause less record wear.

After a company decided on manual or automatic sequence, production of that title generally stayed in the same configuration indefinitely. Notable examples of albums using automatic sequence include the 1968 Reprise Records release, Electric Ladyland, by Jimi Hendrix which was still sold in automatic sequence well into the late 1980s. Other common examples include Frampton Comes Alive by Peter Frampton, Songs in the Key of Life by Stevie Wonder, Quadrophenia by The Who, and Bad Girls by Donna Summer.
