Using Built-in Songs to Master Keyboard Play
To master a song, it is best to break it up into shorter parts 
(phrases), master the phrases, and then put everything 
together. Your Digital Keyboard comes with a Step Up Lesson 
feature that helps you to do just that.
The built-in songs are pre-divided into phrases to help you 
master keyboard play.Step Up Lesson takes you through practice of the right hand 
part, left hand part, and both hand parts for each phrase of a 
song. Master all of the phrases and you master the song.
