What does the time signature "4/4" indicate?

The time signature "4/4" is one of the most common time signatures in music, often referred to as "common time." It indicates that there are four beats in each measure (the top number) and that the quarter note receives one beat (the bottom number). This means that in each measure, you can fit four quarter notes, which helps musicians maintain a steady rhythm and plays a crucial role in the structure of the piece.

This time signature is foundational in many styles of music, ranging from classical to pop, because it allows for a clear and consistent meter that is easy for performers to follow. Understanding the relationship between measure and note values is key to interpreting and performing music accurately.
