When the under 2 ft crowd is near me and a piano it’s good times. Their impulse is to smash the keys with fists something I have a little experience with. Pleased to improvise with them, they’re speaking my language. The kid seems to understand hand hits keys/ sound happens. That’s a great place to be and encourage. Lots of time later for shaping it elsewhere.
Often parents are in two camps. They either get it and let us smash clusters together or they’re upset, apologetic and doing their best to take Jr.’s attention elsewhere or they physically remove them.
