Can you provide an explanation of the time signature used in this piece of music?

The time signature in music tells us how many beats are in each measure and what type of note gets one beat. It is written as two numbers stacked on top of each other. The top number indicates the number of beats in a measure, while the bottom number represents the type of note that gets one beat. For example, in 4/4 time signature, there are 4 beats in a measure and a quarter note gets one beat.
