It's hot, too hot for the UK, too hot for children to be in school and then be expected to play piano. Yesterday I almost decided not to bother. Instead, and I'm not certain this should ever be regarded as a good way to practice, we played "strip piano". It's like strip poker but without the gambling.
Completing each task in her practice (carefully bundled into the correct number of activities) entitled Mathilda to remove one item of clothing. By the end she was stark naked and rushed off to put clean, cool clothes back on.
There's something to be said for this, beyond the fact that we got it done. I really could see if she was sitting properly: there's no way of hiding a slouch if you're shirtless. I think her awareness of her body and her posture was increased.
Not to be done in public and it helps that Mathilda's only six and hasn't learned to be self-conscious about her body.
