Thanks to all who have given me tuning tips! Here are some questions: 1) I tried to reduce false beats by seating the strings on the bridge. However, the bridge on my "PSO" is hard to reach. Part of the treble bridge is directly behind the keyboard and you can't get to it from below or from above. Advice? What tools (makeshift or otherwise) do you use to seat strings on the bridge? 2) I have heard that rust can cause false beats. And I found a little rust on the strings. I'm having a hard time not just spraying WD40 in there. I recall hearing someone say a while ago that WD40 should not be in, on, or near a piano. That's a shame. And it's also a shame that duct tape has limited use inside a piano (perhaps it could replace leather on hammers!) But at least you get to use epoxy in pianos! Anway, what do you use to clean off rust? 3) For a flat piano, how flat must it be in order for it to need a pitch raise? I discovered that it's true that if you tune a flat piano up to pitch, it comes out flat! But I have also discovered that it gets better and better each tuning. Charles Neuman Plainview, NY
