Christmas is a time of year when miracles traditionally happen. It certainly does in this house as here is a picture of my daughter Eleanor playing the double bass in her school orchestra. Since I have never seen her practising the thing this is something of a miracle. It seems our strategy of choosing the double bass has paid off as the bass line usually has long low simple notes, not like the fiddly complicated bits played by the violins which obviously need more practice. Here is a silly picture of the person in question which she secretly took last night while my camera was out.
