Saxophone right hand key noise and bounce..
A lot of manufactures and repairmen let the cork under the right hand keys bounce against the main body of the saxophone. This creates two things: Noise and bounce in the right hand keys when they are lifted. The fix is very simple: just glue a piece of soft felt to the main body of the saxophone under the key. The noise will likely go away and it might help a little with the bounce of the keys in the right hand.
