Now have the complete pattern: all four chords and how they are linked with single notes from the C major scale.

Now we can focus on putting it all together rhythmically in time. Take your time and be patient. Do each part of the exercise until you can get from one chord to the next smoothly and confidently. Make sure that you only play the whole exercise as fast as you can play the slowest part. Then gradually build speed until you can play the whole thing at at a steady, consistent tempo.

In the long run, it is more important to learn the motions properly. That way you will not have to unlearn any bad habits later on when you are trying to learn or play more complicated musical examples.
