I need to understand this rhythm.... please help

Explanation:
One way to simplify rhythms is to subdivide, or break up the rhythm into seperate parts:
A [tex]\frac{4}{4}[/tex] time signature can be broken into sixteens like this:
1 e + a 2 e + a 3 e + a 4 e + a
So the rhythm in measure 53 is counted:
1 + 2 + 3 e + 4 e
