Part 2. What Is a Polyrhythm?
A polyrhythm is when you play two or more different rhythms at the same time. These rhythms usually have different time signatures, which creates a complex and layered sound.
This is used in many types of music, from jazz and classical to electronic and African music.
Polyrhythms are often expressed as ratios, such as 4/3, 5/4, or 32. This means that one rhythm plays 4 beats in the same time as another plays 3.
Polyrhythm vs. Polymeter: What's the difference?
Many people confuse polyrhythm with polymeter, but they are different concepts.
● Polyrhythm is when you have multiple rhythms in different subdivisions all played at the same time.
● Polymeter involves two or more time signatures running alongside each other, but they line up at set intervals.
Example:
● A 4/3 polyrhythm means one voice plays 4 beats while another plays 3 in the same time.
● A 4/4 and 3/4 polymeter means one rhythm follows a 4/4 measure while the other follows 3/4, with longer periods of alignment.

Part 4. FAQ about 4/3 Polyrhythm Generator
1. How to do 4 over 3 polyrhythm?
A 4/3 polyrhythm is when one rhythm plays four beats in the same time that another plays three beats.
Steps to Play a 4/3 Polyrhythm:
1️⃣ Count in Groups of 12: The lowest common multiple of 4 and 3 is 12, so count:
1 - 2 - 3 - 4 | 1 - 2 - 3 - 4 | 1 - 2 - 3 - 4 (for the 4-beat rhythm)
1 - 2 - 3 | 1 - 2 - 3 | 1 - 2 - 3 | (for the 3-beat rhythm)
2️⃣ Make the first beat stronger: Both rhythms should align on beat 1.
3️⃣ Use a 4/3 polyrhythm generator: A tool like 4four.io can help you hear it in real-time.
2. How to clap 3/4 polyrhythm?
A 3/4 polyrhythm (or 3 against 4) is when you play 3 beats in the same time as 4 beats.
● Clap your right hand on every 4-beat cycle (slow and steady).
● Clap your left hand on every 3-beat cycle (a bit faster).
● Both hands meet on the first beat and then follow separate patterns.
3. How to play 4 notes against 3?
This is the same as a 4:3 polyrhythm, but it is used for notes instead of beats.
On a Piano:
● Play 4 evenly spaced notes with your right hand (one per quarter note).
● Play 3 evenly spaced notes with your left hand (slightly slower).
On Drums:
Play 4 hi-hat hits while keeping 3 bass drum hits in the same timeframe.
4. How do you create a polyrhythm?
Making a polyrhythm means combining two different rhythms with different beats.
Ways to Create a Polyrhythm:
● Use an Online Polyrhythm Generator: Try Netlify to create custom polyrhythms.
● Use MIDI in a DAW: Programs like Ableton, FL Studio, or Logic Pro. These programs let you place notes in different time signatures.
● Play by ear: Tapping one hand in quarter notes while tapping the other in triplets and feel the polyrhythm naturally.
