How do you achieve color and interest to the piano songs you are playing? One technique is how you balance the hands. Playing the melody stronger than the accompaniment immediately adds more flavor and color to the music. An easy way to achieve this is to simply apply more arm weight to the right hand while playing.
All instruments essentially imitate the human voice. However, with the piano, every time you play a note, it immediately begins to fade out. One thing I’ve noticed from listening to flute players is that they play higher notes with more breath and volume than lower notes. This is totally natural when singing or playing a wind instrument. One thing to be learned from one of the great piano teachers, Ruth Slenczynska is that you can mimic this effect on the piano. Playing higher notes louder and lower notes softer will add a lot of color and expression to your music. You can also take a bit more time when you reach the higher notes to add a greater effect. You will create the sense of a singing line on the piano!
But let’s not forget about the left hand in all this. If you were using the pedal you could meld the notes to create a nicer sound. Yet without the pedal you can achieve this by holding selected notes with your fingers! Try holding the bottom note holding the first note in each group so it overlaps the following sixteenth notes. You will be rewarded with a rich sound! ~Living Piano, Piano Tips with Robert Estrin
