Who stole my keys
Besides doing their homework, preparing for spelling and other academic chores, Nigel and Shannon have to practice their piano (theoretically) every day. This is no simple matter - there is nagging, shouting and in Shannon's case, often crying and lots of pouting.
If you think that piano lessons are an easy thing that you can leave to the teacher, hoping to convert your child into a natural musician - I would say no. Mozart used to give lessons when he was a kid, and I think even he would have struggled with some of his students, which were probably older than he was. In addition, as a parent, you would have to sit down and watch your child practice everyday, during which you are not allowed to play with your phone.
Not everyone has the music in them, and I believe even though a portion can be taught, some would just have to work a lot harder than others. Take Nigel and Shannon for example - they each have their strengths. Nigel is technically stronger while Shannon is more graceful. Nigel, even though not a musical prodigy, can pick up a piece quickly and read the notes to correct himself. Shannon, on the other hand, becomes a bundle of nerves as she tries very hard to work the piano by hearing and playing "Simon says" on the keys. Once she memorises the piece, she can play it rather well though.
She excels at ballet though and her movements and agility are miles ahead of Nigel's rather awkward dance steps - which is why he's sticking to the keyboard.
