This past weekend, I taught some extra lessons to make up for lessons we'll miss at Thanksgiving and Christmas, and to help prepare for the recital. One student, who is taking off a few weeks around Thanksgiving, had an extra-long lessons, so I decided it was a good time to learn a Christmas carol, since I won't be seeing her as much in early December, when I would normally teach carols. I brought her Deck the Halls and she learned it in record time; I almost ran out of things to teach to fill up the hour lesson.
When I came back for our regular lesson this week, her mom said to me, "Deck the Halls, yeah, she learned that last year." I had printed out the same exact song, from my favorite website, and taught it to her last year. No wonder it was so easy for her to learn! So I said to my student, "I'll bring you a new Christmas song next week," which she took to mean, "you're not allowed to play this one anymore."
Not to worry, Claire, you may still play Deck the Halls - and it sounds so good when you play it! But there's no rule about how many Christmas songs you're allowed to play. I probably play 50 different Carols, so I think you can manage 2 this year.
