Both "indie" and "indie pop" had originally referred to the same thing during the late 1970s. Inspired more by punk rock's DIY ethos than its style, guitar bands were formed on the then-novel premise that one could record and release their own music instead of having to procure a record contract from a major label. According to Emily Dolan, indie is predicated on the distorted music of the Velvet Underground, the "rebellious screaming" of early punk, and "some of rock's more quirky and eccentric figures", such as Jonathan Richman. "Pitchfork"s Nitsuh Abebe identifies the majority of indie as "all about that 60s-styled guitar jangle". Indie pop borrows heavily from Western pop song conventions and structures with extensive use of, for example, major chords, hooks, common time and a "consistent and noticeable rhythmic element" i.e. the beat.
