The piano is one instrument where comparisons between musicians are easier to make. There are no two identical pianos in the world, but the common mechanics, the inability to bend notes (Monk notwithstanding) and the generally untouched, acoustic sound are a better yardstick than any other instrument (the triangle, perhaps) to tell musicians apart—case in point: in 1958-1959, Dave Brubeck and Bill Evans were recorded at the same studio, Columbia's "church" at 30th St., and it's likely that at some point they used the same piano, and yet they're easily identifiable.
