Task 3: African beats

Most songs are in fourths, which means you can count 1,2,3,4,1,2,3,4..... Sometimes a song is in thirds.
In African music these rhythms are often mixed. One drum beats a pattern in fourths, the other in thirds. A very, very simple pattern to demonstrate this is 90 for green and 120 for red. Try different sounds.
If you use different numbers you can get the same pattern, but faster or slower. Write down four combinations of numbers that will give you the same pattern.
