If you have a piano and one of the keys is sticking, it could be due to the regulating screw located in the key. The screw has a flat, threaded end that goes into the key when you press it. If the screw is set improperly, it can cause the key to stick as it gets wedged in the keyhole. To fix this issue, you can use pliers to slightly turn the regulating screw so that its top part lays flat and can easily fit into the keyhole. This is a simple procedure that anyone can do.
Good luck!
