# Rhythmic Perfect Fifth And Fourth Based on the Schillinger system. I don't think these are actually divine like the perfect fifth and fourth. But the system is enjoyable. Maybe you could use these for poetry too. ## Perfect Fifth 3 - - _ _ - - / 2 - - - _ _ _ = 3:2 - - _ - _ _ 2+1+1+2 in 6/8. ## Perfect Fourth 4 - - - _ _ _ - - - _ _ _ / 3 - - - - _ _ _ _ - - - - = 4:3 - - - _ - - _ _ - _ _ _ 3+1+2+2+1+3 in 12/8.
