This occurs in the first two bars of the first part. Instead of playing DBB, DCC, DBB C I come up to the B on the A string and the drop down to the open D. The variation is then BDD, ADD, BAB C.

This occurs in the third and fourth bar of the second part. Instead of playing the Gs on the A string I go up the scale to the high B on the E string and come back down again.
