Dotted notes and ties
A dot adds half the note's own value. A tie joins two notes of the same pitch into one. Both lengthen a note; they are used in different situations.
Note values halve as you go down the ladder: whole, half, quarter, eighth. That gives you 4, 2, 1 and ½ beats — but nothing in between. Dots and ties fill the gaps.
A dot adds half again
A dot after a notehead adds half of that note's own value.
| Note | Plain | Dotted |
|---|---|---|
| Whole | 4 beats | 6 beats |
| Half | 2 beats | 3 beats |
| Quarter | 1 beat | 1½ beats |
| Eighth | ½ beat | ¾ beat |
The dotted quarter followed by an eighth is one of the most common figures in all music. Learn it as a shape rather than recalculating it each time.
Rests take dots too, and the arithmetic is identical: a dotted half rest is three beats of silence.
Double dots
A second dot adds half of what the first dot added — a quarter of the original value. A double-dotted half note is 2 + 1 + ½ = 3½ beats. You will meet these occasionally in classical music and almost nowhere else.
A tie joins two notes into one
A tie is a curved line between two notes of the same pitch. They become a single sound lasting their combined length. You play the first and hold through the second.
Ties exist because bar lines are non-negotiable. A note lasting six beats in a 4/4 piece cannot be written as one symbol across a bar line, so it is written as a whole note tied to a half note in the next bar.
They also handle lengths a dot cannot express — five eighth notes, say — and they keep rhythms readable by letting each bar show its beats clearly.
A tie is not a slur
They look almost identical and mean completely different things.
| Connects | Means | |
|---|---|---|
| Tie | Two notes of the same pitch | One longer sound |
| Slur | Two or more different pitches | Play smoothly, no gap between them |
If the noteheads are on the same line or space, it is a tie. If they move, it is a slur. That check is quick and always works.

- Note values and restsNote values are ratios, not fixed lengths. Each one lasts half as long as the one above it.
- Time signaturesThe top number counts beats per bar; the bottom number says which note value gets the beat.
- Triplets and tupletsThree notes in the space of two. Tuplets borrow a division that does not belong to the current metre.
