Watching Adam Hicks play keyboard in the movie Lemonade Mouth could have triggered Zac's deep interest in the instrument. Zac has been hitting the keyboard at home and singing at the same time, pretending that the beat coming from it matches the song, although I must admit that it is totally not in tune...
Then one night, while Echo was here, Zac, on his own initiative, asked Echo to teach him how to play the keyboard. Echo taught him how to play Twinkle Twinkle Little Stars, and since that night, that's about the only song that can be heard in our house each time Zac turns on the keyboard.
To Echo, Zac wants you to watch this. He's learning to use two fingers to play the same beat but on a different octave. Not sure if I described it correctly, but I remember you mentioning something about octave. :)
