The lyrics of Santana's song "Black Magic Woman" describe the power that a woman holds over the singer. With the repeated declaration "I've got a black magic woman," the singer is expressing his enraptured state, feeling blinded and bewitched by her. He believes that she is attempting to turn him into a devil, because of how she is making him feel. This suggests a sense of danger and risk that accompanies being in her presence. The chorus has a pleading tone, as the singer begs this "magic woman" not to turn her back on him, as he is afraid he may lose her. He warns her not to play games with him, as he is under her spell and she could easily manipulate him.

The lyrics of the song are an example of the themes of mysticism and sensuality that were prevalent in rock music of the late 1960s and early 1970s. The song has been interpreted to be about a specific woman, or about the female form in general as a source of mystical power. The use of the term "black magic" is significant because it has connotations of the occult and supernatural.
