Blues form

Blues form is a musical structure commonly used in blues music, typically consisting of 12 repeating measures or sections. It follows a specific chord progression—often built around the I, IV, and V chords—creating a sense of familiarity and emotional depth. The form usually includes a sequence of phrases that reflect themes of longing, struggle, or resilience. Musicians often improvise around this pattern, allowing for personal expression within a predictable framework. This structure provides a shared language for blues performers and audiences, emphasizing storytelling through music and creating a soulful, expressive sound.
