A whole note is a musical symbol that represents a specific duration of sound. It looks like a hollow oval with no stem, and it lasts for four beats in common time. Whole notes are often used in music to indicate longer sounds, allowing musicians to hold a note for an extended period without interruption. In sheet music, whole notes can be found in various genres, from classical to pop. They provide a sense of stability and can be used to create a calm atmosphere. Musicians, like pianists or guitarists, often use whole notes to emphasize important moments in a piece.
