Jazz is an improvisation-centered music tradition that emerged from African American communities in the early 20th century. It blends blues feeling, ragtime syncopation, European harmonic practice, and brass band instrumentation into a flexible, conversational art. Defining features include swing rhythm (a triplet-based pulse), call-and-response phrasing, blue notes, and extended harmonies built on 7ths, 9ths, 11ths, and 13ths. Jazz is as much a way of making music—spontaneous interaction, variation, and personal sound—as it is a set of forms and tunes. Across its history, jazz has continually hybridized, from New Orleans ensembles and big-band swing to bebop, cool and hard bop, modal and free jazz, fusion, and contemporary cross-genre experiments. Its influence permeates global popular and art music.

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.

Mande music is the courtly and communal music of the Mande peoples (including Mandinka, Maninka/Malinke, and Bambara) whose heartland lies in present‑day Mali and extends across Guinea, Senegal, The Gambia, and Côte d’Ivoire. It centers on the hereditary jeli (griot) tradition of professional praise‑singers and instrumentalists who preserve genealogies, epics, and social histories. Its core sound is built around cyclical ostinati (kumbengo) on instruments such as the 21‑string kora (harp‑lute), the balafon (gourd‑resonated xylophone), and the ngoni (lute), with improvisatory filigree (birimintingo) weaving above. Vocals alternate between composed refrains and free, declamatory passages (donkilo and sataro), often in call‑and‑response with a small chorus. Rhythms commonly breathe in 12/8 and 6/8 feels with subtle cross‑rhythms, while modal tunings (e.g., sauta, tomora) and timbral “buzz” aesthetics (from balafon resonators) shape a distinctive, shimmering texture. Repertoires comprise named pieces tied to lineages and events (e.g., Sunjata epics, Duga, Kaira, Jarabi). In modern contexts, these materials underpin both acoustic ensembles and electrified bands, maintaining the social function of praise and mediation while speaking to contemporary audiences.

Griot (also called jeli/jali) is the hereditary West African tradition of poet-singers, historians, and musicians whose craft combines storytelling, praise-singing, genealogy, diplomacy, and music. It is centered in the Mande world of today’s Mali, Senegal, Gambia, and Guinea, and is best known for virtuosic performances on the kora (21‑string harp-lute), balafon (xylophone), and ngoni (lute), alongside powerful, ornamented vocals. Griot music is structured around cyclical ostinatos with improvisatory flourishes, call-and-response, and text that preserves communal memory—epics, lineages, and moral instruction—delivered in languages such as Mandinka and Bambara. While deeply traditional, the griot aesthetic has adapted to modern stages and studios, influencing global “world music,” West African pop, and blues-derived styles.
