How do you move a piano? Very carefully.
Okay, Im being a little sarcastic, but moving a piano is a serious endeavor.
Im a big advocate of hiring a professional mover to move a piano. Pianos are heavy and its easy to damage a piano while moving it. Im speaking from experience. I own a Kimball piano my parents bought brand new for me when I was a child. That piano was a big deal to me after having played on an old clunker of a piano for several years. I played that new piano every day.
When I got married it was time to move the piano to my own home. My husband and his brothers moved it themselves. It wasnt an easy job even with the moving dolly they used (pianos weigh several hundred pounds grand pianos can weigh 1,500 pounds). The amateur move of my piano resulted in both of the piano legs being damaged (a common occurrence when people move a piano themselves) and some unplanned internal work (some pins needed repair and a string broke). I should have hired a piano mover. Then I wouldnt have had those problems, but my husband and I thought we would save money by doing it ourselves. It was a lesson I should have remembered, but I was foolish a second...
