@bob - So it really does happen? After this incident, it seems to me that piano playing really requires daily maintenance in order to keep it at it's top shape.@kawai - my teacher is the last person I want to inform of this incident, he'll kill me with a thousand needles when he discovers that i lost the technique he taught due to some illness. This is nuts, I'm now really afraid of the piano in a way.Sucks to be me.
