A time signature indicates the value (what kind of
note it is) of the beat (the top number) and the number of beats in the
measure (the bottom number).
The example above and below means that there are 4
'quarter' notes in every measure.
The notes written here are called quarter notes. In other lessons we will learn what other kinds of notes
look like.
Here is an example of a time signature of 3/4. There
are 3 beats in every measure.
