Power pop is a popular musical genre that draws its inspiration from 1960s British and American rock music. It typically incorporates a combination of musical devices such as strong melodies, clear vocals and crisp vocal harmonies, economical arrangements and prominent guitar riffs. Instrumental solos are usually kept to a minimum, and blues elements are largely downplayed.
In the 1980s and 1990s, power pop continued as a commercially modest genre but by the mid-1990s through the 2000s, power pop was mainly in the underground.
While its cultural impact has waxed and waned over the decades, power pop is among rock's most enduring subgenres.
