The accordion is more like plating an organ than a piano, in that it's how long and on some models how far down you hold the keys rather than haw hard you hit them. Iy's not as big a difference as between plucked and bowed strings for example, but maybe like a plucke dstringed instrument carried like a guitar and one operated laid in front of the musician like a zither.
