Music which issues from the Heart is Music with a capital M. No matter how adept one is at playing his instrument; no matter how developed his "technique", it is mechanical noise if it does not "move" the listener in some manner.

I prefer a piece played unskillfully, but with passion, than the most masterful technical performance which lacks emotion.

Of course, the skillful expression of one's heart on any instrument is best.

But, I have wondered, what is it that I actually hear in an impassioned performance that moves me. Without seeing, or even without knowing anything about the performer, I can tell if it is from the heart. Why is this? khandu
