Bill has about 4 different beginning guitar books he uses with Alex. Not all at the same time, of course.
Yesterday Alex composed his first piece, using the notes he's learned thus far.
I am not a musician, so I can't really tell you much about it from a critical standpoint.
As the totally unbiased mother-of-the-composer, though, I can say that the piece is perfect and brilliant.
And the title is "Scratchy, Scratchy, Don't Scratch Me."
