---------------------- multipart/alternative attachment Dear List; I'm having a difficult time with some new Nordiska pianos. Generally, they tune ok, a challenge most of the time (tight pins, rendering problems, etc.), but a few just knock me out. I've found that on these few, I can't seem to stabilize the tuning on the center section of the piano, near the first treble strut. In that area, if I tune one note (unisons included), it affects the other notes around it. If I find that the notes in the piano are flat, I use a pitch raising method and add a few cents as needed. On these, when I get done with the first pass, they are close, but need another going over. And over. And over. If I tune one note, the notes next to it get sharp. If I tune them down, other notes go up. I spent about 2 or 3 HOURS on the one I tuned last Friday. I got it done, finally, but it was a record for me. It wasn't the only one like this. My first attempt was a week ago, when I looked at the pinblock flange fitting with a mirror. There was a nice gap there. So I came back last Friday to insert some shims and try again. I was sure that this would cure the problem. No such luck. I had spent already over an hour the first time, and 2 1/2 hours Friday. I have noticed on these Nordiskas, and some other pianos from the same factory (plates look identical) that they seem to have a lot of interaction between strings. I had one that a high treble string broke, and all the other strings around it went WAY sharp. When I replaced it, they all came back down. It seems that other pianos aren't so much affected by broken strings. These really are too sensitive to changes in tension. I almost expected all the strings around the broken one to pop, like a zipper. I would really like to get to the bottom of this. I work for one of the largest Nordiska dealers in the country, and it's going to kill me unless I can get a handle on what's going on. I can't afford to spend this much time on tuning one piano. Anyone have a similar experience with this? Ideas? Suggestions? Thanks for your consideration.
