The song "River" by Joni Mitchell is a folk song about heartbreak composed in 1971. It features Mitchell's vocals accompanied by intricate piano parts. Though through-composed rather than using a standard verse-chorus form, it centers around the repeated line "I wish I had a river." The song creates a blending of Mitchell's vocals and piano through consistent chord progressions like IV-I, creating a sense of resolution between phrases. It also uses a vi-ii progression to build tension before resolving to the tonic C major chord.
