What type of musical form is typically found in the blues genre?

The 12-bar blues is a structural framework that is fundamental to the blues genre, characterized by its specific chord progression and lyrical format. This form typically consists of three lines of text, where the first line is repeated, followed by a concluding line, fitting into a 12-bar chord sequence that often revolves around the I, IV, and V chords of a key. The format allows for improvisation and expressive lyricism, which are hallmark traits of blues music.

While other forms like AABA, sonata form, and verse-chorus structure may appear in various genres or songs, they do not encapsulate the essence of the blues in the same way that the 12-bar structure does. The 12-bar blues not only defines the harmonic framework but also serves as a canvas for artists to convey emotional depth, making it a cornerstone of blues music.
