Rhythm Basics: Quarter, Eighth, and Sixteenth Notes

Rhythm is a blueprint for when sounds happen, and the units of that blueprint are note values: lengths that tell you how long each hit lasts. There are really only three you need at the start. A quarter note fills one beat, an eighth note fills half, and a sixteenth fills a quarter. Get those three under your belt and you can read the rhythm of almost any pop, rock, or funk pattern.

Hear it first

These lengths click into place the instant you watch them light up.

1. Open the Rhythm Pattern Dictionary
2. Select Rock and press play; the hi-hat lands on every other cell (8th notes)
3. Switch to Funk and listen again; the hi-hat now fills every cell (16th notes)
4. Slow the tempo to around 70 BPM and notice how the spacing of the hits matches the counting below

Keep that contrast in your ear as you read on. The grid is just note values made visible.

Quarter Notes

A quarter note fills one beat. In 4/4 time, four quarter notes fill one bar.

Beat 1  Beat 2  Beat 3  Beat 4

When you count “1 – 2 – 3 – 4,” each number is a quarter note. It’s also what a metronome clicks on.

Eighth Notes

An eighth note is half the length of a quarter note. Eight fit in one bar.

Count them as “1-and-2-and-3-and-4-and.” Rock guitar strumming and typical pop hi-hat patterns use eighth notes.

Sixteenth Notes

A sixteenth note is half an eighth note — four per beat, sixteen per bar.

Count as “1-e-and-a.” Funk hi-hats and tight drum fills live here.

The Grid Makes It Visual

The Rhythm Pattern Dictionary uses a 16-step grid — one cell per sixteenth note.

Pattern	Hi-hat density	Note value
Rock	Every other cell	8th notes
Funk	Every cell	16th notes
Bossa Nova	Every other cell	8th notes

The difference between rock and funk is largely this: rock uses 8th-note hi-hats, funk uses 16th-note hi-hats. That single change transforms the feel entirely.

What to try next

Keep the three counts handy: a quarter note is “1 – 2 – 3 – 4,” an eighth note splits each into “1-and,” and a sixteenth splits it further into “1-e-and-a.” Then load a pattern, count out loud along with the grid, and try the same pattern at two tempos. Watching the lit cells line up with your counting is where note values stop being abstract.
