When I taught piano, I encouraged the parents to give the kids an opportunity, after they had practiced their lesson material, to just play around on the piano.
- You learn by discovery.
- Playing by ear exercises the improvisation muscles.
- Discovering tunes on your own is enjoyable.
It benefited the children, and, I have a hunch, it would benefit adult pianists as much as kids.
Just a thought.
I encourage you to try it!
Do you play by ear? Do you enjoy picking out songs by ear?
