Music note values tell you how long a note lasts — not how high or low it sounds, but how much time it takes up before the next note begins. They are the rhythm half of written music, and the whole system is built on one simple idea: each note value is exactly half the length of the one above it. Learn that halving pattern and you can read, count and write rhythm with confidence.
If notation has ever looked like a wall of dots and squiggles, this is the part that makes it click. Once you know how long each shape is meant to be held, the page stops being a puzzle and starts telling you exactly when to play. This guide walks through every common note length, the dots and ties that stretch them, the triplets that bend them, and the rests that turn them into silence.
How music note values divide the beat
The beat is the steady pulse you tap your foot to. Note values describe how many beats a note fills, or what fraction of one it takes. The neat thing is that the whole family is a chain of halves — a binary system where every step down is worth half the step above:
- A whole note is the longest common value.
- A half note is half of that.
- A quarter note is half of a half note.
- An eighth note is half of a quarter.
- A sixteenth note is half of an eighth, and so on down to thirty-second and sixty-fourth notes.
The names give the game away. In a standard 4/4 bar — four quarter-note beats to the measure — a whole note fills the whole bar, a half note fills half of it, and a quarter note fills a quarter. If you have read our guide to how many beats are in a bar, this is the same maths seen from the note’s point of view rather than the bar’s.
What each note shape looks like on the page
You can tell a note’s value at a glance from three features: whether its head is hollow or filled, whether it has a stem, and how many flags or beams hang off that stem.
- Whole note (British: semibreve) — a hollow oval with no stem. It looks the most “open” because it lasts the longest.
- Half note (minim) — a hollow oval with a stem.
- Quarter note (crotchet) — a filled-in oval with a stem, no flag.
- Eighth note (quaver) — a filled head with a stem and one flag.
- Sixteenth note (semiquaver) — a filled head with a stem and two flags.
Every extra flag halves the value again, so a thirty-second note carries three flags. When several eighths or sixteenths sit together, their flags join into thick horizontal beams instead — two eighths under a single beam, sixteenths under a double beam. Beaming does not change the durations one bit; it just groups notes so the beat is easier to read. Those American and British names sit side by side in our guide to music symbols if you want the full crossover chart.
Reading note values against a 4/4 bar
The clearest way to feel these lengths is to count them out in 4/4, where one quarter note gets one beat. Say the counts out loud and tap a steady pulse:
- Whole note = 4 beats. Play on beat 1 and hold through “1–2–3–4.”
- Half note = 2 beats. Two of them fill a bar: one on “1–2,” one on “3–4.”
- Quarter note = 1 beat. Four to a bar: “1, 2, 3, 4.”
- Eighth note = ½ a beat. Eight to a bar, counted “1-and-2-and-3-and-4-and.”
- Sixteenth note = ¼ a beat. Sixteen to a bar, counted “1-e-and-a, 2-e-and-a…”
Notice that the number of same-value notes needed to fill one 4/4 bar doubles at every step: one whole, two halves, four quarters, eight eighths, sixteen sixteenths. That doubling is the single most useful fact about note values, because it lets you swap any note for two of the next size down without changing the bar’s total length. Want to hear it rather than read it? Tap the patterns out on the virtual piano against a metronome and the counts will lock in fast.
What a dot adds to a note’s length
A small dot placed just after a notehead lengthens it by half of its own value. That is the only rule, and it applies to every note:
- A dotted half note = 2 + 1 = 3 beats.
- A dotted quarter note = 1 + ½ = 1½ beats.
- A dotted eighth note = ½ + ¼ = ¾ of a beat.
- A dotted whole note = 4 + 2 = 6 beats.
Dotted rhythms are everywhere because they break the plain, even feel of straight halves. The classic “dotted eighth plus a sixteenth” pairing gives you that galloping, slightly swung push you hear in countless rock and pop grooves. A dotted quarter followed by an eighth is the backbone of a huge number of ballad melodies. Once you can spot a dot and add half, these rhythms stop tripping you up.
Tying notes together across beats and bars
A tie is a curved line joining two notes of the same pitch, and it simply adds their durations into one longer sound. A half note tied to a quarter note is held for three beats — the same length as a dotted half, but written as a tie because of where it sits in the bar. Ties are essential for one job dots cannot do: carrying a note across a barline. If you want a note to ring from beat 4 of one bar into beat 1 of the next, you tie the two together, because a single notehead cannot straddle the barline. This is also how you write syncopation, where accents land off the main beats and pull the groove forward.
Triplets and tuplets that bend the halving rule
Everything so far divides the beat into halves and quarters. A triplet breaks that pattern by squeezing three equal notes into the space normally taken by two. An eighth-note triplet fits three eighths inside a single quarter-note beat, counted “trip-a-let” or “1-and-a.” You will see a small “3” bracketed over the group so it is not mistaken for straight eighths.
Triplets are what give a shuffle, a blues, or a swung hip-hop beat its rolling feel, as opposed to the even, machine-like grid of straight sixteenths. The same idea extends to other tuplets — quintuplets pack five notes into a beat, sextuplets six — but triplets are by far the most common, and getting comfortable with them is the biggest leap most beginners make in reading rhythm.
Rests: the silent version of every note value
Silence is written too, and every note value has a matching rest of exactly the same length. A quarter rest lasts one beat of silence, an eighth rest half a beat, a half rest two beats, and a whole rest a full bar. Their symbols differ from noteheads — a whole rest hangs down from a staff line while a half rest sits on top of one, which is a common point of confusion — but the durations line up perfectly with their note twins. Dots work on rests as well, so a dotted quarter rest is one and a half beats of silence. Rests are not gaps in the music so much as part of the rhythm; the space a good drummer leaves out is often what makes a groove breathe.
Turning note values into real seconds with tempo
Note values are relative — a quarter note is “one beat” — but how long a beat actually lasts depends on the tempo, measured in beats per minute. The sum is easy: one beat lasts 60 divided by the BPM in seconds. At 120 BPM a quarter note lasts 60 ÷ 120 = 0.5 seconds, so an eighth note is 0.25 seconds and a whole note is 2 seconds. At a slow 60 BPM a quarter note stretches to a full second. This is exactly why producers who set delay and reverb times by ear can also dial them in by maths — a note-length delay at 120 BPM is 500 ms for a quarter, 250 ms for an eighth.
Once you can convert values to seconds you can also read them straight off a DAW’s piano roll, where the grid lines mark quarters, eighths and sixteenths. If you would rather hear an idea than sequence it note by note, a tool like Solmi can turn a simple rhythmic sketch into a rough track you can refine. And when you are ready to go deeper into how these values sit inside a bar, the time signature guide and the wider Theory & Songwriting hub pick up right where this leaves off.
Frequently asked questions
How many beats is each note value worth?
In common 4/4 time, where a quarter note equals one beat: a whole note is 4 beats, a half note is 2, a quarter note is 1, an eighth note is half a beat, and a sixteenth note is a quarter of a beat. Each value is half the length of the one above it, so the counts double at every step down the chain.
What does a dot after a note do?
A dot adds half of the note’s own value to its length. A dotted half note is worth 2 + 1 = 3 beats, and a dotted quarter is worth 1 + ½ = 1½ beats. The rule is identical for rests, so a dotted quarter rest is one and a half beats of silence.
Why do American and British note names differ?
They describe the same durations with different traditions. American names are fractional — whole, half, quarter, eighth, sixteenth — which makes the halving obvious. British names are older terms: semibreve, minim, crotchet, quaver and semiquaver. A quarter note and a crotchet are exactly the same length; only the label changes.
