There are so many ways you can take this and I had so many photo ideas but when I told my husband about the ideas, he came up with another one, and his is a really good, so here it is...
...You need to breathe deeply when playing a brass instrument, even with little lungs! Little Miss P doesn't play very many notes but does have a few blows of the cornet when Mr P is practicing. It's sweet seeing her take that first deep breath to get the sound out as it is hard (I have tried a few times and am not that great at it!).
