Every 16th Note Drum Groove: 8,195 Bass Drum Patterns in 4/4 + Free Worksheet
8,195 Drum Grooves in 4/4: The Complete 16th Note Bass Drum Worksheet!
How many drum grooves are actually possible?
If you limit yourself to just bass drum placements on 16th notes in a single bar of 4/4, the number gets big fast. There are 16 possible positions in the measure, and each one has two choices. Play it or don’t.
That gives you:
65,536 total possible bass drum combinations
That’s already far beyond what anyone could reasonably practice or even write out.
Now take it one step further. If you allowed every voice to vary freely. Bass drum, snare drum, and hi-hat, all on 16th notes. Each subdivision has four possible states instead of two.
Now you are looking at:
4,294,967,296 possible grooves
Over four billion!
That’s just 16th notes. No triplets. No orchestration. No dynamics. Just raw placement.
So yes, it is entirely possible to play a groove that nobody has ever played before!
Why 8,195 Grooves Instead of 65,536?
This system narrows things down to something usable.
Instead of including all 65,536 possibilities, these grooves follow two practical rules:
Every groove includes a bass drum on beat 1
No bass drum notes land on beats 2 or 4 where the snare drum sits
Those two constraints eliminate a massive amount of clutter while keeping grooves musical and realistic.
What remains is:
8,195 unique 16th note bass drum grooves
Then a small collection of common bonus grooves are added, bringing the total to:
8,217 total grooves!
These include patterns that are common in real playing but technically break the rules, so they are included on purpose.
Not Sheet Music. A Better System.
Writing out 8,000+ measures of drumset sheet music would be impractical. You would be flipping through pages for days.
Instead, the entire system is built into a spreadsheet, which turns out to be far more powerful.
It’s not just a list. It’s scrollable and searchable. It also allows for a randomized groove generator to highten your practicing!
How to Read the Drum Groove Spreadsheet
The layout is simple once you understand what you are looking at.
Each row represents one complete groove.
Across each row are 16 cells, one for each 16th note in the measure.
White cell = no bass drum
Black cell = bass drum note
At the top, the counts are labeled so you can track where you are in the measure. The beats are clearly marked, and beats 2 and 4 are highlighted in orange to show where the snare drum belongs.
Because of the rules used to generate the system, most grooves avoid placing bass drum notes directly under those snare hits. This keeps everything feeling clean and playable.
To the right of each row:
Some grooves include a short description
Some have recognizable pattern names
Some are marked with actual song names that use that groove
That last column is an ongoing project. If you recognize a groove in a song, you can contribute and help expand the list.
The Random Groove Generator
At the top of the spreadsheet, there is a random number generator.
Click it, and it jumps you to a completely random groove.
This is where things get interesting.
Instead of defaulting to familiar patterns, you are forced into something new. Sometimes it will feel awkward. Sometimes it will sound great. Occasionally, you will land on something you would never have come up with on your own.
That is the point.
If you are writing a song and need a fresh idea, this is a direct path to one. Click the generator, play the groove, and build from there.
How to Practice These Drum Grooves:
There are a few ways to approach this system depending on your goal.
1. Random Challenge Mode
Use the generator and commit to learning whatever shows up. No skipping.
2. Scroll and Discover
Jump to a random section and work through a handful of grooves in that range.
3. Density Training
As you scroll further down, the number of bass drum notes gradually increases. Early rows are sparse. Later rows become dense and physically demanding.
This creates a natural progression from simple to advanced without needing separate exercises.
4. Composition Mode
Use the spreadsheet as a writing tool. If you are stuck, grab a random groove and build a beat or song around it.
You will end up with ideas that do not sound recycled.
Why This Works
Most drummers rely on familiar shapes. That is not a bad thing, but it creates limits.
This system removes those limits by:
Forcing exposure to uncommon patterns
Building independence across all 16th note placements
Strengthening timing in uncomfortable spots
Expanding your internal vocabulary of grooves
It is both a practice system and a creative engine.
The Bigger Picture
Even with 8,217 grooves mapped out, you are still only scratching the surface.
Remember:
65,536 total bass drum possibilities (16th notes only)
Over 4 billion possible full-kit grooves
That does not include triplets, dynamics, orchestration, or phrasing
So if you are chasing originality, you are not running out of options anytime soon.
You are barely getting started!
