Four-four time, also known as common time, is a musical meter that consists of four beats in each measure. Each beat is represented by a quarter note, making it easy to count and play. This time signature is widely used in various music genres, including pop, rock, and classical. In sheet music, four-four time is indicated by a "4/4" at the beginning of a piece. Musicians typically emphasize the first beat, creating a strong rhythmic foundation. This structure allows for a steady and predictable flow, making it accessible for both performers and listeners.
