Pay particular attention to beat one in this pattern. As it takes up a full beat the tendency often is to race on to the second beat.
Keep the eight note down up momentum even when you don't strike that eighth note after beat one.
Notice the dot attached to the first note - this sign adds half the value of the note that it is attached, therefore the first note in this rhythm is worth one and a half counts (three eight notes).
This one may take a little time, but work through slowly through the example using our counting method, and it should all fall into place.
