What is a dotted note?
A tiny dot beside a note has a big job: it makes the note longer. It's one of the most useful symbols in rhythm, and the rule behind it is wonderfully simple — the dot adds half. Learn that one sentence and dotted notes are yours.
A dotted note is any note with a small dot placed just to the right of its head. That dot isn't decoration — it's an instruction that changes how long the note lasts. Here's the only rule you need: a dot adds half the note's value to itself.

The one rule: the dot adds half
To find the length of a dotted note, take the note's normal value, cut it in half, and add that half back on. In plain math: dotted note = note + half the note. That's it. The dot is always worth half of whatever note it sits next to, so a dot beside a big note is worth more than a dot beside a small note.
Dotted half note = 3 beats
A half note normally lasts 2 beats. Half of 2 is 1, so the dot adds 1 beat: 2 + 1 = 3 beats. You play a dotted half note once and hold it for three full counts. In 3/4 time a single dotted half note fills the whole measure — which is why it shows up so often in waltzes.
Dotted quarter note = 1½ beats
A quarter note lasts 1 beat. Half of 1 is half a beat, so the dot adds half a beat: 1 + ½ = 1½ beats. The dotted quarter is everywhere in pop and folk music, and it almost always teams up with an eighth note to round out two beats: a dotted quarter (1½) plus an eighth (½) equals 2 beats. Counted in eighths, that's "1 & 2" with the note struck on "1" and held through the "&."
Dotted eighth note = ¾ of a beat
An eighth note lasts half a beat. Half of a half is a quarter, so a dotted eighth lasts ½ + ¼ = ¾ of a beat. It's usually paired with a sixteenth note (¼ beat) to fill one whole beat — the snappy "long-short" pattern you hear in marches and lots of rock grooves.
How to count dotted notes
The reliable trick is to count in the smallest note value present, then hold across the right number of those small beats:
- Dotted half (3 beats): count "1, 2, 3" and replay on the next "1."
- Dotted quarter + eighth: count "1 & 2 &," play on "1," hold through "&," replay the eighth on "2."
- Dotted eighth + sixteenth: count "1 e & a," play on "1," hold through "e &," replay the sixteenth on "a."
Counting in the small subdivision keeps the dotted note from drifting long or short — the most common dotted-rhythm mistake.
A quick practice plan
- Say the math out loud — "half note is 2, dot adds 1, so 3."
- Tap and count in the smallest subdivision before you play.
- Drill the long-short pairs (dotted quarter + eighth, dotted eighth + sixteenth) slowly.
- Quiz the symbols out of order until a dotted note's value is instant.

Frequently asked questions
What does a dot after a note mean?
A dot to the right of a notehead increases the note's length by half its original value. So the dotted note lasts the original note plus half of it again.
How long is a dotted half note?
In 4/4 time a half note is 2 beats, and half of that is 1 beat, so a dotted half note lasts 3 beats. You play it once and hold it for three counts.
How long is a dotted quarter note?
A quarter note is 1 beat and half of that is half a beat, so a dotted quarter note lasts one and a half beats. It is often followed by an eighth note to complete two beats.
