Perfection in Piano

There is a difference between knowing how to play a piano piece and knowing how to play a piano piece well. Knowing how to play a piano piece is knowing how to play it smoothly, knowing how to hit all the notes, and knowing how long to hold the notes, so on. But playing a piece well is very different. If you know how to play a piece well, you not only hit all the notes correctly for the right length and play it smoothly, but you add feeling in the music. If there are dynamics written into the music like pp or f or rit., those were put there for you to follow. If there are no dynamic notes for you to follow, you can always make the piece more interesting by slowing a certain part down, or making a certain part just a little bit louder. Then even though you may be playing a really simple song, you will have perfection in the music!
