I just recently discovered w/ myself that while playing, weight coming from the arms, and shoulder is bad as it makes the touch harsh. All weight must rest into the hands/fingers more specifically. Is there any ways to relax more the arms and shoulders?
There is one way to practice relaxing the arms and shoulder, which let me first say is a fantastic way, as it will improve the quality of your sound, and also will eventually teach you how to properly use your body weight in conjunction with the rhythm and phrasing of whatever music you are playing. The way is vibrato. Please read on!
Nobody would be demented enough to say that making a vibrato on the piano keys produces a vibrato sound. However without question the vibrato motion is the best way to learn how to apply weight, and then release it. Playing without natural weight motions can lead to ugly sound, and playing with lots of weight and no release will also lead to ugly sound.
The vibrato motion is akin to a dog shaking himself free of water after a rain. Imagine what a dog looks like shaking out, play a large chord with your right or left hand, at first alone, and then shake it out. With your fingers on the keys, shake it out, shake out the tension, shake out the weight, pretend like your arm is covered in drops of water and you are a dog shaking it out. Then try the left. If you are right-handed, it is harder to use vibrato motion on the left, but you can learn, and it will help to coordinate your piano playing in general. Try both at the same time. This is also difficult, but will also help for hand independence.
How is this applicable to pieces? Imagine a piece with a lot of heavy chords, like the opening of the Tchaikovsky cocnerto (first concerto). To get the best quality sound, I mean come on, pianists just pound these chords out without
any consideration of a deeper sense of sound quality - practice very slowly, and vibrato on each chord. You will hear it in a new way, this I promise. You will have a more beautiful, balanced sound, which you are then free to manipulate as far as voicing is concerned, and within the larger phrase. Leon Fleischer, though not known for his intepretations of music in this sphere, was right when he said, "The chords have to be a planet away from each other." Too often you hear these chords without any distinction, but actually they should sound far apart, a grand, raising motion, like the lifting and waving of a great flag.
Vibrato!
