Pop music 1950 - 1970
Rock 'n Roll began in the 1950s. The new music used fast dance rhythms and gritty instrumental sounds. The first big Rock 'n Roll hit was 'Crazy, Man Crazy' by Billy Haley and the Comets in 1953.
Rock 'n Roll was a marriage between a variant of black Blues music, Rhythm 'n blues and white American folk or Country music. It also took in elements of Gospel music and Western swing. Rock 'n Roll typically used the basic Blues chord sequence, played fast on the guitar.
Elvis Presley, Buddy Holly and Chuck Berry were the biggest stars of 1950's Rock and Roll. The tempo was around 120 BPM, much faster than the blues. This music was for dancing to.

As well as the Blues chord sequence, Rock 'n Roll typically featured a repetitive walking bass line.

Rock 'n Roll bands frequently used the electric guitar, a new instrument in the 1950's, together with the piano, string bass and drums.
Many new and different styles of popular music developed during the 1960s, in the aftermath of Rock 'n Roll. For example:

The Rolling Stones
| Instrument | How it was used |
|---|---|
| Electric guitar | Developed by Les Paul and first popularised by the American Fender company. Could be either loud and aggressive (eg Jimi Hendrix) or subdued and lyrical (much of The Beatles). Often there were two - the rhythm guitar playing rhythmic chords together with the drum kit, and the lead guitar playing solos and riffs [Riff: A short phrase that is repeated, normally with improvisation and often referred to in jazz music. ]. |
| Keyboards | Many bands used Hammond organs or electric pianos because they were easily transported while on tour. |
| Drum kit | Provided the all-important beat. Main components are the bass drum, the snare drum and the hi-hat (two cymbals on a stand that can be operated by foot pedal). |
| Strings | Beginning with The Beatles, some bands began to use violins, violas and cellos to add depth and colour to the sound. |
Music recording:
Recorded music became in many ways more important than live music during the 60's. The Beatles experimented with recording techniques to reverse, speed up, slow down and add electronic effects.
