Ok, you got your left hand doing 4 beats, you got your right hand doing 3, at the same time. You see it in all sorts of music. Try this with your hands on your desk and beat out the rhythms. The first beat is always together, then the rest are not going to line up, so when you put them together there is a certain pattern that someone has changed into the pattern of a sentance.
So, when you say 'Pass the goll darn butter', our hands are tapping together on pass, then right left right left right, in much the rhythm of the sentence. Try it over and over to get it.
To start really simply, you could also say 'alligator alligator aglligator alligator' for 4 sets of 4 16th notes.
Make sense?
