The next exercise in Fig. 4 is an “endless” loop, which will virtually never be played the same way twice. This is much harder than the previous exercise because we‘ll just be playing a constant stream of eighth-notes. When it comes time to move to a new key/chord, we’ll just move to the nearest available note and continue on our new pattern. The skill here is being able to “see” the chord you’re going to while forgetting about the one you’re on (though still being able to play on it). This is possibly an even harder mental exercise than a physical one.
