Music notation uses time signatures to indicate rhythm. A time signature provides information about the rhythm in a song and the division of the beats. A time signature always appears at the beginning of a score, next to the clef. There are two numbers stacked on top of one another to make up the time signature symbol. I will explain to you what those numbers mean in this article.
What do the numbers in the time signature mean?
I’d like to discuss the measure before we get started. Music is measured in bars, which are time units that are organized into groups. Essentially, it is a structure for organizing our musical ideas. As you divide your song into bars, you can think of them as blocks.
In the same way, measures are like sentences in a paragraph. You can use the time signature to find out how many words and how long each sentence is. You will be able to see how many beats there are in each measure and how long they are.
Complex Time Signatures and Tempo
Time Signatures
The only measures we have looked at so far are those in 4/4, which have four quarter notes in each measure. Measures can also be in 3/4, with three quarter notes per measure. These ratios are called “time signatures”, or “meters”. In a time signature, any positive integer can be used in the numerator: 1/4, 2/4, 3/4, 4/4, 5/4, etc. Time signatures are valid when the denominator is a power of two: so 2/2, 5/8, and 17/16 are valid, but 4/3, 2/7, and 8/5 are not.
Tempo
There is one more aspect of rhythm to consider: speed. You can have a fast beat and a slow beat at the same time. Tempo is the speed at which the beat moves. BPM, or beats per minute, is the most commonly used tempo measurement in music. In other words, if your beat is a quarter note, like 4/4 or 3/4, a tempo of 60 BPM means there are 60 quarter notes per minute, or one quarter note every second.
In a tempo of 60 BPM, you will have 60 eighth notes per minute, which means 30 quarter notes per minute, or one quarter note every two seconds. When discussing tempo, musicians often omit the letters “BPM”, saying instead things like “quarter notes equal 90” or “eighth notes equal 135.”
What’s the Difference Between Tempo and Time Signature?
Music Time signature and tempo are two different parameters in a piece. Together, they generate a piece’s beat, speed, and “feel,” but their combined effects can be quite different.
Fast or slow 4/4 is determined by the time signature, and the tempo determines if it is fast or slow.” The use of tempo rubato is one example of blending the beat with the tempo. Using tempo rubato, performers make stylistically appropriate micro-changes to their tempo.
As a rule of thumb for tempo rubato, the beat can be bent but never broken, which means that even if the tempo is briefly slowed or accelerated, the listener should always be able to feel the beat. Piano music by Frédéric Chopin famously features tempo rubato as a common performance practice.
How Does Tempo Work With Time Signatures?
Beats per minute, or BPM, are used to measure tempo. Playing music, however, requires that you also take into account the song’s time signature. A time signature is an indication of how many beats are played in a measure, which is crucial to creating rhythm in music. A stacked number, such as 3/4 and 4/4, consists of two numbers stacked on top of each other.
Top number indicates the number of beats per measure, and bottom number indicates how long each beat lasts. In 4/4 time, which is also called common time, there are four beats per measure, each represented as a quarter note. In other words, a piece played at 120 bpm in 4/4 would allow for 120 quarter notes within a minute.
Tempo indications are generally constant, except when moving between movements. On the other hand, time signatures are counted differently depending on the needs of the piece. By keeping tempo constant, we are able to be more lenient and free-flowing in other areas.
A composer may introduce a new tempo indication in sheet music by using a double bar line, oftentimes with a new key signature or time signature as well.
You intuitively understand different tempos, even if you’re new to music theory. It’s because of this that you’re able to clap to just about any song. Throughout our lives, we are familiar with the concept of pacing and work within the parameters set by a tempo.
A ticking clock can even be used to compare tempo and BPM. A clock ticks at precisely 60 BPM because a minute is composed of 60 seconds. There is an inherent connection between time and tempo. Higher BPM songs can energize us, so it makes sense that they make us feel energized. A new, faster pace is literally beckoning.
When playing a piece of music, musicians often use metronomes or click tracks in the best DAWs to keep time and rhythm, although this counting is usually internalized or reflected by the conductor.

Quick Questions
What is the tempo of 3/4 time signature?
There are three beats per measure in a 3/4 time song and they are counted 1, 2, 3, 1, 2, 3, and so on. In addition to this time signature, it is also known as the waltz rhythm.
What effect does tempo have on time signatures?
To begin with, we need to clarify something important: Time signatures do not determine the speed at which music is played. A piece’s tempo determines the speed or slowness of the music.
How do you tell time signature from tempo?
In order to determine duration in terms of time, it is necessary to check the tempo. When the time signature of a song is 4/4 and the BPM is 60, each quarter will last 1 second if the unit of measure is a quarter. The quarter will last 0.5 seconds if the time signature is 4/4 and the BPM is 120.
What is the difference between tempo and timing?
Timing refers to executing swing movements in the proper order. The speed of the swing is called the tempo.
