Blues is an African American musical tradition defined by expressive "blue notes," call-and-response phrasing, and a characteristic use of dominant-seventh harmony in cyclical song forms (most famously the 12‑bar blues). It is as much a feeling as a form, conveying sorrow, resilience, humor, and hard-won joy. Musically, blues commonly employs the I–IV–V progression, swung or shuffled rhythms, and the AAB lyric stanza. Melodies lean on the minor/major third ambiguity and the flattened fifth and seventh degrees. Core instruments include voice, guitar (acoustic or electric), harmonica, piano, bass, and drums, with slide guitar, bends, and vocal melismas as signature techniques. Over time the blues has diversified into regional and stylistic currents—Delta and Piedmont country blues, urban Chicago and Texas blues, West Coast jump and boogie-woogie—while profoundly shaping jazz, rhythm & blues, rock and roll, soul, funk, and much of modern popular music.

Country blues—also called rural blues or folk blues—is the earliest widely documented form of the blues, rooted in the everyday music-making of African Americans in the rural American South. It typically features a solo singer accompanying themselves on acoustic guitar, with flexible time, expressive vocal delivery, and abundant use of blue notes. While 12‑bar structures are common, country blues often stretches or compresses measures to fit the lyric, making phrasing elastic and conversational. Regional flavors emerged—Delta (driving, droning thumb bass and slide), Piedmont (ragtime‑inflected fingerpicking), and Texas (looser phrasing and single‑string leads)—but all share storytelling lyrics about work, travel, love, hardship, and spiritual longing.

Delta blues is a raw, emotionally direct style of country blues that emerged in the Mississippi Delta—an alluvial plain stretching from Memphis to Vicksburg. It is typically performed by a solo singer accompanying themselves on acoustic guitar, often with bottleneck slide. Hallmarks include expressive, speech-like vocals; flexible, rubato timing; insistent thumb-driven bass patterns; syncopated treble figures; and frequent use of open tunings. Lyrics are vivid and personal, touching on hardship, migration, love, work, spirituality, and folklore. Though commonly framed by 12‑bar and 8‑bar blues forms, Delta blues thrives on elastic phrasing, blue notes, and call-and-response between voice and guitar. Its sound is earthy, gritty, and intimate—music for porches, juke joints, and field gatherings—yet it became one of the most influential sources for electric urban blues and rock.

East Coast blues (often overlapping with the Piedmont blues tradition) is a ragtime‑inflected, guitar‑driven branch of early country blues that flourished along the U.S. Atlantic seaboard from Virginia and the Carolinas down into Georgia and, by migration, up to urban centers like New York and Washington, D.C. It is distinguished by syncopated fingerstyle guitar—an alternating, steady thumbed bass line with off‑beat, ragtime‑like treble figures—paired with the core blues vocabulary: call‑and‑response phrasing, blue notes (flattened 3rds, 5ths, and 7ths), and common 12‑bar and 8‑bar progressions. Grooving “shuffles,” walking or alternating bass patterns, and conversational harmonica or second‑guitar lines reinforce a buoyant, danceable feel. Lyrically it spans traveling tales, topical verses, humor, and personal narratives, delivered with a relaxed but rhythmically intricate swing.
