I have a beautiful grand piano, but am downsizing my living space for a couple of years. I have a large storage space at the new place but it is not air conditioned and it is always very dry (no humidity at all) and sometimes very hot (up to 100 degrees). Would it be safe to store my piano there without damaging it?

I want to move a grand piano about 15 feet. It has wheels, but they will leave marks in the floor if the piano is rolled. Are there small dollies made for supporting piano legs?

Is it essential for learning piano further (meaning the touch etc.)? Does it make you a better and more sensitive player? And is it easier to play other pianos after playing a grand? I've played for 10 years now. I have a not-so-good beginner upright and I feel it's slowing down my progress. I'm thinking of a second-hand yamaha c2 or c3. Thanks.

When I choose ANY of the piano voices, it sounds muffled - like a synthesized keyboard kind of sound. But when the demo plays, it sounds like a real grand piano. Is there some other setting I need to turn on or off to get this to sound like a real piano? Thanks!
