Melisma is a vocal technique where a single syllable of text is sung over multiple notes. This expressive style is often found in various musical genres, including Gregorian Chant, R&B, and Middle Eastern music. It allows singers to showcase their vocal agility and emotional depth, creating a rich auditory experience. In melismatic singing, the embellishment of melodies can convey different feelings and enhance the overall performance. Famous examples can be heard in the works of artists like Mariah Carey and Whitney Houston, who use melisma to add complexity and beauty to their songs.
