Your Piano 27 does not have a good seal, Lee. You didn’t say which model Piano 27 you have. In most cases, the melodica has a gasket that seals the reed chamber and that can be replaced by a new gasket that you make. If you do a search for “gasket” in these forums, you’ll find many posts about replacing a gasket. It’s not hard, though it may be more so if your instrument is the original metal body Piano 27.
