An incantation is a set of words, often chanted or spoken rhythmically, that are believed to have magical or supernatural effects.

A recitative is a vocal style in opera and oratorio that imitates the natural inflections of speech and is used for dialogue or narration, not for magical purposes.
When you encounter questions about musical or cultural terminology related to magic or ritual, remember that incantation specifically denotes words with supposed magical power.
