Building a beat from a grid

A drum groove is a pattern of hits in time. This builder shows it as a grid: rows for each drum sound, columns for sixteen steps in a bar. Click a cell to add or remove a hit, choose a preset to start from, and press play to hear your groove. Sixteen steps means each step is a sixteenth note, so four steps make one beat and sixteen steps make one bar of four-four time.

The rows are kick, snare, hi-hat, open hi-hat, clap and tom. The kick is the low thump, the snare is the crack on beats two and four, the hi-hat ticks the subdivisions, and the open hat and clap add colour. Start from a preset, change one row at a time, and listen to how each change alters the feel. That is how drummers and producers actually write grooves.

The classic grooves

Rock puts the kick on beats one and three, the snare on beats two and four, and the hi-hat on every eighth note. It is simple, solid, and it works for thousands of songs. Funk keeps the snare on two and four but moves the kick to syncopated sixteenths and adds ghost notes and open hats. Boom bap, the classic hip-hop groove, uses a swung hi-hat, a kick that lands slightly late, and a snare that cracks on two and four.

Four on the floor puts the kick on every beat, which is the foundation of dance music, with the snare or clap on two and four and the hats off the beat. Halftime puts the snare only on beat three, which makes the groove feel twice as slow and twice as heavy, and it is the basis of trap and dubstep. The Latin preset mixes a syncopated kick with a steady snare and a patterned hi-hat for a dance feel.

Swing and feel

Swing delays every second sixteenth note, so the groove leans and lurches instead of marching evenly. A little swing makes a groove feel human; a lot of swing makes it feel drunk in the best way. Hip-hop and funk live on swing, while rock and dance music usually stay straight. The swing slider in this builder shifts the off sixteenths later, so you can hear the difference from straight to heavily swung on the same pattern.

Feel also comes from velocity, how hard each hit is played, and from tiny timing differences that real drummers add naturally. This builder plays every hit at the same level, which is fine for writing, but a real performance varies. When you take a groove to a real kit or a recording, play the snare backbeats firmly, ghost notes quietly, and hats with a relaxed wrist.

Writing your own groove

Start with the skeleton: kick and snare only. Get those two rows feeling right before adding anything else, because they carry the groove. Then add hi-hats on eighth notes, and listen: does the groove need more hats, or fewer? Add open hats or claps one at a time, and remove anything that fights the kick and snare. The best grooves are often the simplest ones, with one surprising hit that makes them memorable.

Try moving one kick hit by a single step and listen to how much the groove changes. A kick one sixteenth early creates urgency; one sixteenth late creates a laid-back drag. Those tiny moves are the difference between a groove that feels mechanical and one that feels alive. Save patterns you like by screenshotting the grid, and build a small library of grooves you can return to.

Tempo

Tempo changes everything. A groove at 70 beats per minute feels heavy and spacious; the same pattern at 140 feels urgent and driving. Hip-hop often sits between 70 and 100, rock between 100 and 140, and dance music between 120 and 140. The tempo slider in this builder lets you hear your groove across that range. When a groove feels wrong, try a different tempo before changing the pattern: the pattern may be fine and the tempo may be the problem.

Practise playing along with the builder at a slow tempo first, then raise it gradually. Drummers build speed by playing cleanly at slow tempos, not by forcing fast ones. If you play an instrument over the groove, start at a tempo where you can play every note cleanly, then raise it five beats per minute at a time.

Common mistakes

Filling every step, so the groove has no space to breathe.
Putting the snare anywhere but beats two and four in a basic groove.
Adding swing to a straight style, or playing straight in a swung style.
Changing five things at once instead of one row at a time.
Judging a groove at the wrong tempo instead of trying a better one.

How to use this builder

Pick a preset close to the style you want, press play, and change one row. When the groove feels good, try a different tempo and a little swing. When it feels great, screenshot the grid and use it as the basis for a song, a practice routine, or a drum part. The grid is a writing tool, not a performance: the goal is a groove you can play, feel, and remember, not just one that looks good on screen.
