Hi GMC'ers! Welcome to the second lesson about polyrhythms. Here we will see the same polyrhythms of the previous lesson (4 against 3, 4 against 5 and 4 against 6) but with the subdivision of each member into 8th notes. That would be: if the polyrhythm was 4 against 5 the 5 quarters are divided into 8th notes leaving ten 8th notes over 4 quarters but remember that those ten 8th notes are into a rhythm of 5 quarters that goes against the normal 4 quarter pulse.
In the case of 4 against 3 and 4 against 6 it's almost the same but the internal accents are what it's important here. When you divide the half note triplet into quarters you have the same polyrhythm as 4 against 6 and the 8th notes are the same amount of that last one that I've mentioned. So the important thing would be the accent. In the 4 against 6 the 8th notes are accented every two 8th notes but in the 4 against 3 are accented every four 8th notes.
I hope you enjoy the lesson :)
