In this chapter, Sami dives deeper into applying polyrhythms in a live context by using different subdivisions to shift between rhythmic feels. The core idea is to train your internal time by using the bass line to anchor the quarter-note triplet pulse, while the drums and piano maintain the original groove.
This approach lets you move between the feel of sixteenth notes (8 per bar) and quarter-note triplets (6 per bar) or even more complex subdivisions like 9 notes per bar. The result is a flexible rhythmic awareness that helps you transition smoothly across feels.
With the drums anchoring the 4/4 groove and the bass outlining the six-note subdivision, you can freely switch between:
Practicing this way helps you internalize the different feels so you can switch without relying on visual cues or metronome clicks. Eventually, you disable all rhythmic aids and trust your inner pulse and imagination.
The switch between 8 and 9 notes is subtle — and that’s the point. When a musician plays 9 evenly spaced notes across a 4/4 bar, it can almost sound like 8 notes… but something feels “off.” That’s the rhythmic illusion in action.
Sami demonstrates this using short 4-note phrases. When played with 8-note logic, they feel stable and familiar. But when grouped into 9-note logic and divided in 4s, the resulting groove becomes unexpected and strange — even though the notes are placed with perfect accuracy.
The magic happens when you start blending these feels: switching from 8 to 9 and back, while maintaining control. You don’t need to treat this like math — treat it like groove. But mastering the technique gives you expressive power most players never touch.
🎯 Takeaway: Use the bass to anchor triplet feel, switch between 8th, 9th, and 16th-note logic, and trust your internal pulse to move across feels without losing time. That’s where the rhythmic illusion becomes music.
