This exercise is a variation of the Basic Major 1-5 Exercise. Both hands occupy the same five-finger pattern; however, the left hand begins in the middle of the pattern while the right hand starts at the beginning of the pattern. Start slowly and make sure your fingers play precisely together.
You can vary this exercise by playing E, F, G, F, E, D, C in the left hand at the beginning instead of what is shown. Try switching the two parts so that your right hand begins in the middle of the pattern.
Five different keys are notated; however, you should continue the pattern until you have covered every key.
