The Folk Lore of John Lee Hooker

Chicago blues is an electrified, urban form of the blues that took root on Chicago’s South and West Sides during the Great Migration. Built on the 12‑bar blues and I–IV–V harmony, it is marked by amplified guitar, amplified harmonica ("harp"), piano, bass, and drum kit, with a swinging shuffle feel and a strong backbeat. Riffs, call‑and‑response between voice and lead instruments, and terse, memorable hooks are central. Lyrically, Chicago blues pivots from rural imagery to city life—work, love, nightlife, tough luck, and resilience—delivered with grit, wit, and emotional directness. The sound is raw yet powerful, merging Delta roots with urban rhythm sections and studio production that foregrounds groove and bite.

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.

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.

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.

American folk music is a broad family of traditional and vernacular musics that developed in the United States from the 19th century onward, drawing on British Isles balladry, African American spirituals and work songs, Native American traditions, and frontier songs. It is typically acoustic, emphasizing voice and narrative over virtuoso display. Common instruments include acoustic guitar, banjo, fiddle, harmonica, mandolin, dulcimer, and upright bass. Forms are often strophic with repeated refrains, and melodies frequently use pentatonic or modal scales (Mixolydian, Dorian). Lyrical themes range from love, labor, faith, migration, and rural life to topical protest and social justice. Regional styles—such as Appalachian ballads and string-band music, cowboy songs of the West, maritime shanties of New England, Cajun and Creole influences in Louisiana, and Midwestern and Southwestern dance tunes—sit under the umbrella of American folk, which later fed revivals and singer‑songwriter traditions.
