Instrumentals are musical compositions that primarily feature instruments without vocal accompaniment. They can be found in various genres, including classical, jazz, rock, and electronic music. Instrumentals allow listeners to focus on the melody, harmony, and rhythm created by the instruments, showcasing the musicians' skills and creativity. These pieces can serve different purposes, such as background music for films, commercials, or video games. Famous examples of instrumentals include Beethoven's Symphony No. 9, Miles Davis's "So What", and The Shadows' "Apache". Instrumentals can evoke emotions and tell stories purely through sound, making them a unique form of artistic expression.
