Your best music will always come when you are in the moment and just playing the piano. Why is this? Because you have forgotten about trying to make music. Instead, you are now "making" music. A subtle but crucial difference that can be detected by most careful listeners.
The key to being in the moment when playing piano comes when the technical aspects are mastered and the player can just play. Think of sports as an example. Michael Jordan didn't have to think about how to drive the basketball to the hoop. He had done it thousands of times. Now he could allow his intuition to guide him in making the best shot.
If Andre Agassi had to think about how to hit the tennis ball, he never would be able to get it to where he wanted it.
The good thing about New Age piano playing is that technique is easily learned. For example, in the lesson "Reflections in Water," you have 4 open position chords to play. Once the technical aspects of playing these chords is down, you are free to allow your feeling to guide you in making music.
Now you are "in the moment" and can let the music tell you where it wants to go - not the other way around
