Can you explain how time signatures work in music?

Time signatures in music indicate the number of beats in each measure and the type of note that receives one beat. The top number represents the number of beats in a measure, while the bottom number indicates the type of note that gets one beat. For example, in 4/4 time, there are 4 beats in a measure, and a quarter note receives one beat. Different time signatures can create different rhythmic feels in music.
