Johann Pachelbel's Canon in D major, written in the mid-Baroque period and revived from obscurity in the 1960s, has been credited with inspiring pop songs.
Some pop songs borrow its chord progression, bass line, or melodic structure, a phenomenon attributed to the memorability and simplicity of the work. The Canon also shares roots with other, more significant chord progressions that lay the foundations of modern pop music. Its perceived ubiquity is itself an object of cultural discussion.
