Side play is the side to side movement of a key that occurs when the key bushings are not tight enough. This leads to a rocking which can make the key difficult to control or bump into its neighbouring keys. A key that has the correct amount of side play will barely move side to side. Ways to solve side play include adjusting the front rail pin so the rocking motion is reduced, and rebushing keys so that they have new tight bushings.
