This is a follow-up to my post on the scale game. I'll be using scale degrees (1 for the tonic, 8 for high Do, 9 for high Re, and so on) to post the melody under the lyrics. Play the piece in C Major first, and then go on to whatever scale you're practicing for the week. Sing the lyrics as you play. As I see this post in Edit mode the scale degrees seem well aligned under the lyrics. But the formatting goes awry when I hit "publish." I apologize for that, and hope this is not too difficult to read.
