Is the snare on 3 or 2 and 4?
In most genres, the snare is found on beats 2 and 4 (the backbeat), providing a sense of push and forward motion.
Is the snare on the down beat?
Usually you have a snare drum beat that is directly below the X on counts 2 and 4. This is called a "BACKBEAT" as you learned in lesson one. By adding bass drum on downbeats in the first example on this page we now have a complete backbeat using three limbs!
