Sound layering is a technique used in music and audio production where multiple sound elements are combined to create a richer and more complex auditory experience. By stacking different sounds, such as melodies, harmonies, and rhythms, producers can enhance the overall texture of a piece. This method allows for greater depth and variation, making the music more engaging. In sound layering, each individual sound is carefully chosen and placed within the mix to complement others. For example, a vocal track might be layered with instrumental sounds and background effects to create a fuller sound. This approach is commonly used in genres like pop, rock, and electronic music.
