The dot after a note
A small dot directly after a notehead adds half of that note's own value on top. One rule, and it works on every value.
- a dotted half note = 2 + 1 = 3 beats
- a dotted quarter note = 1 + ½ = 1½ beats
- a dotted whole note = 4 + 2 = 6 beats (only in a bar long enough to hold it)
- a dotted eighth note = ½ + ¼ = ¾ of a beat
The dot is exactly half again — never a vague "a little longer."
A dotted half fills the bar with room to spare
The dotted quarter + eighth — the one you'll meet most
This is the "long–short" limp of a march or a carol. The dotted quarter holds through beat 1 and half of beat 2; the eighth lands on the "and".
Straight, then dotted — hear the limp arrive
In a real tune
Ode to Joy's second phrase ends on a dotted figure: four steady notes, then a stretched note, a clipped one, and a long one to close.
The usual mistake
Two versions. Playing the dotted quarter as a full two beats — forgetting the dot is only half again. Or evening it out to "long–long" and losing the limp entirely. Both are fixed by saying the count aloud with the "&" in it: "1 – & 2", and the note ends exactly on the "&".
Try
Clap four even quarters, then clap the dotted version (dotted-quarter, eighth, dotted-quarter, eighth) at the same tempo. Switch between them a few times without the pulse changing.
