Theat the beginning of a composition gives information about how notes will be counted in the music.

The term you are referring to is called the time signature. The time signature is typically placed at the beginning of a composition and consists of two numbers stacked on top of each other, such as 4/4 or 3/4. The top number represents the number of beats in each measure, while the bottom number represents the note value that receives one beat. For example, in 4/4 time signature, there are four beats per measure, and a quarter note receives one beat. This information helps musicians understand how to count and interpret the rhythm of the music.

The time signature at the beginning of a composition gives information about how notes will be counted in the music. It consists of two numbers stacked on top of each other. The top number indicates the number of beats per measure, while the bottom number represents the type of note that receives one beat. For example, in a 4/4 time signature, there are four beats per measure, and a quarter note gets one beat. This means that each measure will typically contain four quarter notes, or a combination of notes that adds up to four beats.
