The tracks labelled Audio Example 13-1 you’ll hear pulses - these are moments in time that are equidistant from one another. This forms the structural backbone of rhythm.  You’ll also hear “The One” this is the beginning of the cycle and serves as the starting point of specific rhythmic structures.  Together the pulse and the One form the expectations that to which rhythmic tension resolves. 

The tracks labeled Audio Example 13-2 subdivide the pulse so that each pulse is two units of time. First listen to The One, the Pulse, the counted eighth notes, and the eighth note pulse played sections so that you can see how they fit into the larger structure. Then remove the Pulse and the counting section and add just the Upbeat track. Listen for how the upbeat relates to the One. Practice clapping or playing the upbeat on a drum while keeping track of the pulse and the one with your body. This begins the process of being able to embody and sustain rhythmic tension.
