The name "PING" came from the sound that Solheim heard as the metal struck the ball. Popular musician-golfer Murray Arnold shared in 1960 that the clubhead, on striking the ball, rings out with the 440 pitch used in tuning pianos. By the end of 1960 Solheim had 6 designs, intentionally muffled the "ping", and had made over 2,000 putters in his garage.
