The primary goal of Book Three is to teach you to play directly from the hymnal. The first thing you must realize is that the music in the hymnal is not written for piano. It is written for voices singing in four part harmony. Therefore, if you were to play exactly what is written in the hymnal, it usually would not sound right on the piano. For this reason, your right hand will be playing exactly what you see on the page in the hymnal at this point, but your left hand will continue playing the chord and octave patterns that you learned in Book Two.
