 Later rockabilly acts, particularly performing songwriters like Buddy Holly, would be a major influence on British Invasion acts and particularly on the song writing of the Beatles and through them on the nature of later rock music.Doo-wop was one of the most popular forms of 1950s rhythm and blues, often compared with rock and roll, with an emphasis on multi-part vocal harmonies and meaningless backing lyrics (from which the genre later gained its name), which were usually supported with light instrumentation.Its origins were in African-American vocal groups of the 1930s and 40s, such as the Ink Spots and the Mills Brothers, who had enjoyed considerable commercial success with arrangements based on close harmonies.
