Gene Vincent - Be-Bop-A-Lula

"Be Bop A LuLa" is good example of a song using a shuffle rhythm (think "Yellow Jackets") and the traditional 12 bar blues form.

12 bar blues is a structure that was frequently used in popular music in the beginning of the Rock n' Roll movement that continues to be employed in song writing. It is a 12 measure structure utilizing the three main chords in a key signature (I=tonic, IV=subdominant, V7=dominant seventh). The V7 chord will always lean towards the I, or tonic. This brings us back to the original key at the end of every song.
