Well into week 4 lesson, it is becoming clear that Shinn wants the student to play piano - a lot. There are more songs assigned this week and additional playing by going back over all the previous lessons and applying the new chord inversions and swing bass to them. By doing this, your hands continue to build keyboard confidence by the sheer act of playing - a lot. Also, you will be getting early experience in arranging "on the fly" as you apply new techniques and inversions to already learned tunes, making them fresh. The more you play, the better you get, and this course provides plenty of opportunity to play.
