It would be great if the two of you could start jamming together. Motivational, great learning experience and all that stuff. It is a great way to work on timing.
To my ears the piano is the ultimate instrument.
If you get someone behind it that is a master at playing it and connecting with the crowd the sky is the limit. When I was a kid I was a paper boy and there was an old, to me then, lady on my route that was practicing when I knocked at the door to collect for the months paper. I commented on her playing and she asked me in to listen. I sat there for quite a while listening and more than once I felt tears running from my eyes that I never knew where coming. I asked her where she had played before and she said never just plays because she likes it.
Piano was the first instrument I learned to play. I took it for 2.5 years, stopping during the summer when I was six. My sister stopped so, so did I. Music was the first written language I learned to reed.
I have read you play piano, have you learned to read music play the piano?
