Back in the fall, I printed out music from G Major music theory for Rachel.  Hmm, it must have been around Christmas, because I remember going there looking for Jingle Bells.  She has since subjected treated us to plinking out the music by ear, not by reading the music!  It has been SO frustrating for me, but I let it go.
She did practice, a bit, now and then, but she always preferred to play by ear.
This week, she's been pestering me for more music.  I told her she couldn't have more until I heard her play the ones she had using the right fingerings, etc.

She did it!  She struggled just a little on things in the last two songs that would have been easy to correct, if I had known she was practicing the music.  So, she has six more songs to practice, this time with two hands.
