[Leslie Bartlett]

Some topics run on past demise, then continue the same heading while 
wandering far from the trail. I didn't wish to do this.   The problem is 
in the top two octaves, and I don't think it's a bridge pin problem. I 
first blamed myself, but then knew I couldn't be that bad, so when the 
piano teacher said the octaves were dropping within a couple days, I 
then knew the problem was structural, but just haven't been able to 
think of what. i go back Friday to attempt to diagnose the problem, 
having given up on my own paranoia................
