An extremely popular form of music derived from jazz in the 1950s and became known as Rock & Roll. The jazz elements in early Rock & Roll are obvious: instrumentation, swing eighth notes (compound subidivison), twelve-bar blues form.
Later Rock & Roll abandoned the compound triplet feel of jazz and began to use straight eighth notes. The introduction of electronic amplification changed the sound of this music.
As Rock & Roll developed, it commonly incorporated a 16-bar form called Song Form: a variation of 12-bar Blues where the first four measures are repeated to create an AABA structure.
Popular Rock & Roll artists include Elvis Presley, Johnny Cash, Jerry Lee Lewis, Carl Perkins, Chuck Berry, and many others.
