Time Signatures & Note Values

What Is a Time Signature?

The two numbers at the start of the music

A time signature is the pair of numbers you see at the very start of a piece of music, just after the clef and key signature. It looks like a fraction — 4/4, 3/4, 6/8 — and its job is to tell you how the beats are organised. Music is divided into equal chunks of time called bars (Americans call them “measures”), marked off by vertical bar lines. The time signature tells you two things about every bar: how many beats it contains, and what kind of note counts as one beat.

Think of it as the rule that governs counting. Once you know the time signature, you know how to count the bar — “1, 2, 3, 4” for 4/4, or “1, 2, 3” for a waltz in 3/4 — and that count is the steady framework everything else hangs on. The notes inside the bar can be long or short, but together they always add up to exactly what the time signature demands. A bar of 4/4 always contains four crotchet beats’ worth of notes and rests, no more and no less.

One thing the time signature does not tell you is how fast to play. This is the single most common misunderstanding beginners have about it. A piece in 4/4 could be a slow, mournful ballad or a frantic punk song — the time signature only sets how many beats fall in each bar and which note gets the beat, never their speed. How fast those beats go is set separately by the tempo marking: a word such as Adagio (slow) or Allegro (fast) written above the stave, or a precise metronome mark like ♩ = 120, meaning 120 beats per minute. So the 3/4 in a waltz tells you to count in threes, while the tempo marking tells you whether those threes drift along gently or race past. You will find the common speed and expression words — and how to read a metronome mark — explained in our musical terms and tempo markings glossary.

The time signature appears only once, at the beginning, and stays in force until a new one is written. Most songs keep the same time signature from start to finish, which is why 4/4 is so common that it is also called common time and is sometimes written as a large letter C. Before we can count a bar, though, we need to know how long each note lasts — and that is what note values tell us.

Note Values Explained

Crotchets, quavers, minims and the rest of the family

A note value is the length of a note — how many beats you hold it for. In the UK we use a set of traditional names that describe the whole family of durations, each one exactly half the length of the one above it. This halving relationship is the key to the entire system: once you know a crotchet is one beat, you know a quaver is half a beat and a minim is two beats, because each step up or down doubles or halves the duration.

Every note has a matching rest — a silence of exactly the same length. A crotchet rest is one beat of silence, a minim rest is two beats of silence, and so on. Rests are not gaps to be rushed through; they are counted just as carefully as notes, because rests re creative and deliberate use of silence. We look at rests in more detail further down.

How Many Beats in a Bar — and in Each Note

The questions everyone asks, answered directly

How many beats are in a bar? It depends entirely on the time signature, because the top number is the answer. In 4/4 there are four beats in a bar; in 3/4 there are three; in 2/4 there are two; in 6/8 there are six quaver-beats that group into two main beats. There is no single universal answer — reading the top number is the answer.

How many beats is a crotchet? A crotchet is worth one beat whenever the bottom number is 4 (so in 4/4, 3/4 and 2/4). It is the natural pulse of most music — the beat you tap your foot to. How many beats is a minim? A minim is worth two beats — as long as two crotchets. How many beats is a semibreve? A semibreve is worth four beats, filling a whole bar of 4/4 by itself. Going the other way, a quaver is worth half a beat, so two quavers fit inside one crotchet beat.

The reason these answers all assume “crotchet = 1 beat” is that the bottom number of the time signature decides which note is the beat. With a 4 on the bottom the crotchet is the beat. With an 8 on the bottom (as in 6/8) the quaver becomes the counting unit, and the beat values shift accordingly — which is exactly why compound time can feel confusing at first. The interactive chart below lets you change the time signature and watch the beat values update, which is the quickest way to make this click.

Note Values Chart

Every note name, its beats and its matching rest in one place

This is the complete note values chart for reading rhythm. It lists each note from longest to shortest with its UK name, its American name, how many beats it lasts when the crotchet gets the beat (a bottom number of 4), what it divides into, and the rest of exactly the same length. Bookmark it as a quick reference whenever you are reading or writing music.

Remember that the beats column assumes the crotchet is one beat. When the bottom number of the time signature changes — for example in 6/8, where the quaver is the basic unit — the same notes are worth different amounts. You can keep the same printable version of this chart to hand: it is included in the free downloadable reference further down the page.

Reading the Two Numbers

Top number, bottom number, and what each one controls

A time signature is not really a fraction, even though it looks like one. The two numbers do completely separate jobs, so read them as a pair of instructions rather than as a division sum. Choose a top and a bottom number in the tool below, and the annotations update to show exactly what each one is telling you to do.

The Top Number: How Many Beats

The top number tells you how many beats are in each bar. A 4 means four beats per bar; a 3 means three; a 2 means two. This is the number you count up to before starting again at 1. When you tap your foot and count along to a song, the number you reach before the count resets is the top number of its time signature.

The Bottom Number: Which Note Is the Beat

The bottom number tells you which note value counts as one beat. Think of the bottom number as a symbol:

• 2Minim (half note)
• 4Crotchet (quarter note)
• 8Quaver (eighth note)
• 16Semiquaver (sixteenth note)

In 3/4 the beat is a crotchet, so you count three crotchet beats. In 6/8 the bottom 8 means the underlying unit is the quaver. In 2/2 — known as cut time — the minim is the beat, which makes the music feel fast and striding even when the notes look the same on the page.

Simple Time vs Compound Time

The difference is how each beat divides

Once you are comfortable counting, there is one more distinction that explains the “feel” of a piece: whether it is in simple time or compound time. The difference is simply how each main beat splits into smaller notes.

Simple Time: Beats Split Into Two

In simple time, each beat divides naturally into two equal halves. 4/4, 3/4 and 2/4 are all simple time: each crotchet beat splits into two quavers, which is why you count the subdivisions as “1-and-2-and”. The vast majority of pop, rock and folk music is in simple 4/4. If the top number is 2, 3 or 4, the music is in simple time.

Compound Time: Beats Split Into Three

In compound time, each beat divides into three equal parts instead of two. The most common compound time is 6/8. A bar of 6/8 contains six quavers, but they are not counted as six separate beats — they group into two main beats of three quavers each. Each main beat is a dotted crotchet (worth three quavers), and the music has a rolling, lilting swing as a result. 9/8 has three such groups, and 12/8 has four. The quick test: if the top number is 6, 9 or 12, the music is compound and you count it in groups of three.

This is the single most useful thing to understand about the 6/8 time signature: it looks like it should have six beats, but it is felt and conducted in two. Get that, and compound time stops being intimidating.

3/4 vs 6/8 — Why They Sound Different

This is one of the most common questions in all of rhythm, and for good reason: both 3/4 and 6/8 contain exactly six quavers per bar, so on the page they can look almost interchangeable. They feel completely different to play, because those six quavers are grouped differently.

In 3/4 there are three crotchet beats, and each crotchet splits into two quavers — three groups of two, with strong beats on 1, 2 and 3. That is the ONE-two-three lilt of a waltz.

In 6/8 there are two dotted-crotchet beats, and each splits into three quavers — two groups of three, with strong beats on 1 and 4. That is the ONE-two-three-FOUR-five-six swing of a jig.

Worked Examples: 4/4, 3/4 & 6/8

Three time signatures, three songs you already know

The fastest way to internalise a time signature is to attach it to a song you can already hear in your head. Here are the three you will meet most often, each counted through with a familiar example.

4/4 — Four Crotchet Beats (“Common Time”)

4/4 means four crotchet beats in every bar. You count “1, 2, 3, 4” and start again. It is by far the most common time signature in popular music. Michael Jackson’s “Billie Jean” is a textbook example: that famous steady kick-drum pulse is the four crotchet beats, with the snare cracking on beats 2 and 4 (the “backbeat”). Tap a steady four and you will find the whole song locks straight onto it.

One bar of 4/4 — four equal crotchet beats, strongest on beat 1.

3/4 — Three Crotchet Beats (Waltz Time)

3/4 means three crotchet beats per bar: “1, 2, 3”. The first beat is strong and the next two are lighter, which gives the gentle swaying feel of a waltz. The clearest example is Happy Birthday — sing it and you will feel a natural three-beat lilt, with the strong beat landing on the important syllables. Most Viennese waltzes, including Strauss’s “Blue Danube”, are in this same three-time.

One bar of 3/4 — three crotchet beats, with the weight on beat 1.

6/8 — Six Quavers, Felt in Two (Compound Time)

6/8 contains six quavers, grouped into two beats of three: “1-2-3 4-5-6”. You feel two main pulses per bar — each a dotted crotchet — with a rolling triple subdivision underneath. The Animals’ “House of the Rising Sun” is the classic example: its rippling arpeggiated guitar is six quavers per bar falling into two groups of three. The Beatles’ “Norwegian Wood” has the same lilting compound feel. Count the two big beats, not all six, and the swing appears.

One bar of 6/8 — six quavers in two groups of three; the two accented quavers are the main beats.

Hearing the difference between these three is a skill in itself. If counting along to a track is still hard, our guide to developing a sense of rhythm has exercises that build the internal pulse everything else depends on.

Odd & Irregular Time Signatures

Beyond the basics — when the beats won’t divide into twos or threes

Once simple and compound time feel comfortable, there is a whole world of odd (or irregular) time signatures to explore. An odd metre has a number of beats that will not split evenly into groups of two or three, so the beats fall into uneven clusters instead — which gives the music an asymmetric, slightly off-kilter feel.

5/4 — the most famous odd metre

5/4 has five crotchet beats in a bar, usually grouped as 3+2 or 2+3 for a lopsided pulse. The best-known example is Dave Brubeck’s Take Five, written by saxophonist Paul Desmond; the theme from Mission: Impossible is also in 5/4.

7/8 and 7/4

7/8 sits at the heart of much Balkan folk music and has been embraced by progressive rock and jazz. It is usually grouped 2+2+3 or 3+2+2, giving a rhythm that feels as though it has an extra kick at one end of the bar. Pink Floyd’s Money stays in 7/4 for most of its length. A free transcription of the saxophone solo on Money is available here.

5/8, 11/8 and beyond

5/8 works like 5/4 but with the quaver as the beat unit, and turns up in Eastern European folk, prog and contemporary classical music. Longer irregular metres such as 11/8 and 13/8 appear in progressive rock and modern jazz, where players stack uneven groups of twos and threes into complex, driving patterns.

This time signature chart pulls everything together: the type of each metre, how many beats it holds, which note value gets the beat, how that beat subdivides, and the feel it creates.

*7/8 is felt as three uneven beats (2+2+3); beat counts for irregular metres depend on how the bar is grouped.

Dotted Notes, Ties & Rests

Three tools for lengthening and shaping rhythm

Dotted Notes: Add Half Again

A dot written immediately after a note adds half of that note’s value back on. A dotted minim is worth 2 + 1 = 3 beats (so it fills a whole bar of 3/4). A dotted crotchet is 1 + ½ = 1½ beats — and, crucially, the dotted crotchet is the natural beat of compound time. A dotted quaver is ½ + ¼ = ¾ of a beat, most often paired with a semiquaver in that characteristic “long-short” dotted rhythm.

Ties: Join Notes Across the Beat

A tie is a curved line joining two notes of the same pitch, telling you to hold them as one continuous sound — you play the first and let it ring through the second without re-articulating. Ties exist mainly to carry a note across a bar line, or to make a length that no single note value can express. A crotchet tied to a quaver lasts 1½ beats, just like a dotted crotchet, but a tie can also stretch a note from one bar into the next, which a dot cannot.

Rests: Counted Silence

Every note value has a matching rest of the same duration: a crotchet rest is one beat of silence, a minim rest two beats, a semibreve rest a whole bar. Rests are counted exactly like notes — the pulse never stops, you simply do not play on those beats. Beginners often rush through rests; resist that. Counting the silences accurately is what makes a rhythm feel solid rather than scrambled.

Famous Songs in Each Time Signature

The fastest way to hear each metre in action

Listening to real music is the quickest way to internalise how a time signature feels. Put these on, count along, and pay attention to the accent pattern and the way each beat subdivides.

Songs in 6/8 Time

• “Nothing Else Matters” — Metallica. The arpeggiated intro spells out the two groups of three perfectly — a textbook 6/8 in rock.
• “We Are the Champions” — Queen. The swaying, anthemic chorus is driven entirely by its 6/8 lilt.
• “Norwegian Wood” — The Beatles. A loose, folk-flavoured 6/8 carried by the sitar line.
• “House of the Rising Sun” — The Animals. The arpeggiated organ makes the 6/8 pendulum swing unmistakable from the first bar.
• “Hallelujah” — Leonard Cohen. The 6/8 metre gives this much-covered song its hymn-like quality.

Songs in 12/8 Time

• “At Last” — Etta James. The classic 12/8 blues ballad: four beats per bar, each with a natural triplet swing.
• “Perfect” — Ed Sheeran. A modern pop ballad that leans on 12/8 for its dreamy, flowing feel.
• “Can’t Help Falling in Love” — Elvis Presley. The triplet subdivision gives it that gentle, rocking-chair sway.

Songs in 3/4 Time

• “Waltz for Debby” — Bill Evans. An elegant jazz waltz — essential listening for anyone exploring 3/4.
• “My Favorite Things” — John Coltrane. Coltrane turns the Rodgers & Hammerstein waltz into a modal-jazz epic.

Songs in Odd Time Signatures

• “Take Five” — The Dave Brubeck Quartet (5/4). Written by saxophonist Paul Desmond — the most famous odd-time jazz piece ever recorded.
• “Money” — Pink Floyd (7/4). The bass riff is in 7/4, switching to 4/4 for the guitar solos.

How to Practise Reading Rhythm

Turning theory into a skill you can use at sight

Understanding note values on paper is only half the job. Reading rhythm fluently — seeing a bar and instantly knowing how it sounds — is a physical skill built through a few simple habits.

Count Aloud and Tap the Pulse

This is the single most valuable rhythm exercise there is. Tap a steady beat with your foot or hand, and count the bar out loud over it: “1-and-2-and-3-and-4-and”. Saying the subdivisions out loud forces you to place every note in time rather than guessing. It feels slow at first, but it builds an internal clock that you will rely on for the rest of your playing.

Separate Rhythm From Pitch

When a passage is rhythmically tricky, put the notes aside completely. Clap or tap just the rhythm until it is secure, then add the pitches back in. Trying to solve rhythm and pitch at the same time is what makes sight-reading fall apart — so don’t. Our guide to sight reading goes deeper into this “rhythm first” approach.

Use a Metronome Once the Rhythm Is Known

A metronome is a superb tool, but use it after you understand a rhythm, not before. Work the bar out by counting first; once it is secure, set our online metronome slow and play along, nudging the tempo up only when every beat is even and unhurried.

Connect Rhythm to the Bigger Picture

Rhythm is one pillar of musicianship; pitch and harmony are the others. Pair this guide with how to read music to master the pitch side of the page, and when you are ready to see how keys and scales fit together, the circle of fifths maps the harmonic side of music just as clearly as this guide maps the rhythmic side — or look up any individual chord shape on our interactive piano chord finder. And if keeping a steady internal pulse is the part you find hardest, the exercises in developing a sense of rhythm are the place to start.
