Most cannot be carried.
They are easy to move if you have the right equipment.
I’ve moved grand piano’s baby grands and uprights.
Worst one I ever moved was a player piano.
Lots of brass and wheels
The upright we have had small roller wheels and troughed the old hardwood floors when we moved it to install new hardwoods. It came back into the room on a path of plywood with quilts under the plywood. Currently sits on a piece of brown masonite hardboard on the new floor. A total pain in the keister.
We would never have made it if it had been a grand or baby grand.
Moved one baby grand with a school friend when his family moved a few blocks in our small town. It was ungainly & awkward but pure teenage bullheadedness overcame the challenges. So glad both locations were ground floor.
