Four-four time, often written as 4/4, is a common time signature in music. It indicates that there are four beats in each measure, and each beat is a quarter note long. This structure provides a steady and familiar rhythm, making it easy for musicians to play and for listeners to follow. In four-four time, the first beat is typically emphasized, creating a strong downbeat. Many popular songs, classical pieces, and dance music use this time signature, making it one of the most recognizable in Western music. Its simplicity allows for a wide range of musical expression and styles.
