This typically involves a key signature comfortable for guitar or piano (like A major, E major, or related minors), often utilizing dominant 7th chords even on the tonic and subdominant. The tempo is probably moderate, suitable for a shuffle rhythm, although slow blues (60-80 BPM) is also common. The time signature is almost universally 4/4, but the rhythmic feel often incorporates swing or shuffle eighth notes. Core instrumentation usually includes electric guitar (often lead and rhythm), bass, drums, and vocals, with harmonica being a frequent addition. The mood is central to the genre, typically evoking soulful, melancholic, or raw emotional expression, sometimes with a sense of catharsis or resilience. The defining structure is the repeating 12-bar blues progression, which forms the basis for verses and instrumental improvisation sections.
