A time signature tells you the rhythmic feel of a piece — how many beats per measure and which note gets the beat. This guide walks you through every common meter with audio examples you can play instantly.
A time signature (also called a meter signature) is the pair of stacked numbers you see at the very beginning of a piece of sheet music, right after the clef and key signature.
It answers two questions at once:
Think of a measure (bar) as a container — the time signature defines its size and what fills it. Every measure in a piece must add up to exactly the number of beats the time signature specifies.
Let's decode 3/4 as an example:
So in 3/4, each measure can hold: 3 quarter notes, or 1 half note + 1 quarter, or 6 eighth notes, or any combination totalling 3 quarter-note beats.
In simple time, each beat divides naturally into two equal parts. The three most common simple meters are:
Four quarter-note beats per measure. This is by far the most widely used time signature in pop, rock, hip-hop, classical, and almost every genre.
Examples: "Twinkle Twinkle Little Star", "Let It Be" (Beatles), "Ode to Joy" (Beethoven), virtually all marches and hymns.
Three quarter-note beats per measure. Creates the characteristic oom-pah-pah waltz feel — strong first beat, lighter second and third.
Examples: "Happy Birthday", "My Favourite Things" (Sound of Music), Strauss waltzes, many minuets.
Two quarter-note beats per measure. Feels brisk and marching — left-right, left-right.
Examples: "Stars and Stripes Forever" (Sousa), polkas, many Latin dances.
In compound time, the main beat divides into three equal parts instead of two. The top number is divisible by 3 (6, 9, or 12), and each group of three eighth notes forms one "big beat."
Six eighth notes per measure, grouped as 2 beats × 3 eighth notes. Each big beat is a dotted quarter note. This creates a lilting, swaying feel — very different from 3/4 even though both have 6 eighth notes per bar.
Examples: "House of the Rising Sun", "We Are the Champions" (Queen verses), "Greensleeves" (sometimes), many Irish jigs.
Nine eighth notes per measure → 3 big beats × 3. Like a waltz where each beat internally sways in threes. Used in some folk music, Romantic-era classical, and progressive rock.
Twelve eighth notes → 4 big beats × 3. Common in slow blues, gospel, and R&B ballads. "At Last" by Etta James and many Motown ballads use 12/8.
Meters where the top number can't be divided into even groups of 2 or 3 create an uneven, propulsive energy. These are called asymmetric or irregular meters.
Usually felt as 3 + 2 or 2 + 3. The most famous example is "Take Five" by Dave Brubeck (in 5/4 as 3+2). The "Mission Impossible" theme also uses 5/4.
Commonly grouped as 2+2+3 or 3+2+2. Think of progressive rock bands like Rush or Tool. Balkan folk music is full of 7/8, 9/8, 11/8, and other asymmetric meters.
Reading about time signatures is one thing — hearing them is everything. Below are real pieces in different meters. Press play and listen for the beat pattern while watching the notes highlight.
Count along: ONE-two-three-four on every measure. The melody lands squarely on the beat.
Feel the waltz swing: ONE-two-three, ONE-two-three. The first beat of each measure is strongest.
This sea shanty has a strong rhythmic drive. Listen for the compound groupings.
This is one of the most common points of confusion for music students. Both 3/4 and 6/8 contain six eighth notes per measure. So what's different?
The key difference is where the accents fall:
A waltz is clearly 3/4 (think: oom-pah-pah). "House of the Rising Sun" is 6/8 (think: da-da-da-DA-da-da). If you can tap two big beats per bar, it's 6/8. If you naturally feel three strong beats, it's 3/4.
Most pieces stick to one time signature throughout, but many compositions — especially in classical, film music, and progressive rock — change time signature mid-piece. The new time signature simply appears at the start of the measure where the change occurs.
