Izaac seems genuinely interested in music and it might be because his grandmother (Shirley) plays the piano so effortlessly (and played by ear at about 3-4 years of age. She now plays be ear or music, and currently plays for two churches.)
Mine has buttons, (because it's electric) but after he pushes a few of those, he does actually try and play the piano. Will he take after grandma and play anything, any time, any where he wants? We all hope so.
I'll probably be less envious of his talent than hers. (It didn't seem fair we practiced and practiced and still didn't sound anything like she did.)
