Vocal harmony refers to the combination of different vocal parts sung simultaneously to create a pleasing sound. This technique is commonly used in various music genres, including pop, rock, and classical. Singers may harmonize by singing different notes that complement each other, often following a specific chord structure. In vocal harmony, singers typically divide into parts, such as soprano, alto, tenor, and bass. Each part contributes to the overall texture of the music, enhancing its emotional impact. Groups like The Beatles and The Beach Boys are well-known for their innovative use of vocal harmony, showcasing its importance in creating memorable melodies.
