In North America, Europe, and Oceania, the decade saw the rise of disco, which became one of the biggest genres of the decade, especially in the mid-to-late 1970s.[1] In Europe, a variant known as Euro disco[1] rose in popularity towards the end of the 1970s. Aside from disco, funk, smooth jazz, jazz fusion, and soul remained popular throughout the decade. It is this influx of popular music that soon transformed into rock and roll during the Early 1970s. Rock music played an important part in the Western musical scene, with punk rock thriving throughout the mid to late 1970s.
