When Eli was small I tried playing the piano to him, and he often cried, which I attribute to his excellent taste in music. It is the appropriate reaction to the noise I make on that thing.... He has shown more interest in playing the piano together, staring at the black and white keys.
Today was an exciting milestone though - he watched my fingers move along the keys (I was playing Jesu Joy of Man's Desiring for the record), and then carefully pressed a key himself. He seemed to now realise the relationship between the piano keys and the music. He continued to play notes, much to Shane's surprise when he came in a few moments later! Very cute.
