Rhythm: beats, beams, and dots
How long each note lasts — the half of notation people skip, then regret.
Pitch tells you which note. Rhythm tells you when, and for how long. Most people learning to read music get comfortable with pitch and quietly ignore rhythm — right up until they try to play with someone else and fall apart. Rhythm is the half that keeps a group together.
The beat is the ruler
Underneath every piece is a steady beat — the thing you tap your foot to. Note durations are measured against it: a note can last one beat, two beats, half a beat, and so on. Nothing about a note's length is absolute; it's always "this many beats," and the beat is set by the tempo.
Halving with beams
Shorter notes are made by dividing. On a staff, flags and beams do the halving: one beam cuts a note to half its length, a second beam halves it again. Numbered notation does the same job with underlines beneath the digit — one line halves, two lines quarter. Same logic, different mark:
- no mark — one full beat
- one beam / underline — half a beat
- two — a quarter of a beat
Beaming also groups notes visually into beats, so a bar of fast notes reads as a few tidy clusters instead of a wall of flags.
Adding with dots
A dot after a note adds half of that note's value back — a two-beat note becomes three, a one-beat note becomes one-and-a-half. A tie joins two notes into one sustained sound across a barline. Between halving, dotting, and tying, you can write any duration you need from a small handful of marks.
Count out loud while you read. It feels remedial and it is the single fastest way to make rhythm stick.
