"Black Magic Woman" is a song written by British musician Peter Green, which first appeared as a single for his band Fleetwood Mac in 1968.

The song is set in common time (4/4), with the rhythm "pushing" on the upbeat, then breaking into a shuffle beat root -chord jam after the final verse.

[3] The song was featured in Fleetwood Mac's live set-lists even after Green had left the band, when it was usually sung by Danny Kirwan.

By the 1987's Shake the Cage Tour, performance of "Black Magic Woman" was blocked by John McVie who felt the song too closely linked to Santana.

[10][11] Santana's version, recorded in 1970, is a medley with Gábor Szabó's 1966 instrumental "Gypsy Queen", a mix of jazz, Hungarian folk and Latin rhythms.

While the song follows the same general structure of Peter Green's version, also set in common time, in D minor and using the same melody and lyrics, it is considerably different, with a slightly altered chord pattern (Dm7– Am7–Dm7–Gm7–Dm7–Am7–Dm7), occasionally mixing between the Dorian and Aeolian modes, especially in the song's intro.

A curious blend of blues, rock, jazz, 3/2 afro-Cuban son clave, and "Latin" polyrhythms, Santana's arrangement added conga, timbales and other percussion, in addition to organ and piano, to make complex polyrhythms that give the song a "voodoo" feel distinct from the original.
