By using our previous polyrhythmic groove ideas we can develop the ability to employ some metric modulation ideas. The key here is to use the polyrhythm as a ‘link’ between the original pattern and the modulation. It’s going to be important to be able to count the quarter notes over the top of these to gain a clear and solid foundation in time.
The first groove is a straight eighth-note triplet groove. Make sure you count a solid and consistent quarter note pulse over the top. Play this as many times as you need to before moving onto example two.
This is where we introduce the polyrhythm, shifting the bass drum to a three pulse over the four quarter notes. Initially begin by continuing to count the original quarter-note pulse. When you become comfortable with this, switch to counting the new six quarter notes that are written underneath the stave.
In this example, we remove the original pulse that we had in example one (where the pulse was grouped into three eighth-note triplets) and shift so the pulse is grouped into two eighth-note triplets. This will make the six-note count feel solid and consistent and you have made the final jump to the modulation.
