---------------------- multipart/alternative attachment David Love says: "Once you correct the pitch and do a fine tuning, all other things remaining constant, the piano will stay in tune." I think so too. My approach is "Rough tune it 'til it stops moving, then fine tune it." Maybe that's once, maybe it's three times - depends on how good my calculations/guesses are for overshoot. However, if I get it settled down (+/- about a cent) before I fine tune, if I go back a year later and the humidity has been kept stable by whatever means, the piano sounds really good. It's less expensive for the client to be paying for rapid pitch adjustments than a full return trip in a few weeks.

My experience says it doesn't matter. Once you correct the pitch and do a fine tuning, all other things remaining constant, the piano will stay in tune. The piano doesn't really settle. Moving the piano cross country may challenge the piano in terms of EMC but nothing more. An upright can go out of tune with a move across the room because the four point weight bearing can tweak the stresses in the case a bit if the floor is not exactly level. The three point weight bearing of a grand makes it immune to such problems.

Terry's post begs the question (and please understand I ain't challingin' nobody on nuttin' ... I'm just seeking information and opinions and science, here) ... Do a piano really need time to "settle" after .. 1. Big pitch change? 2. Small pitch change? 3. Moving it across country? (other than environmental acclimation) 4 Moving it across the room? I have been under the impression--and it may be altogether wacky--that every change that is going to occur in the piano occurs immediatly upon cranking the pin. I thought someone (Dr. Sanderson, perhaps) tested this and proved it. So an adjunct question: Let's say we find a piano 15 cents flat. We pitch correct and fine tune and walk out the door with a follow-up appointment set for three months. When that day arrives, for those who have set such appointments, is the piano any flatter or more sour than it would have been if we found it A440 but still came back in three months? Same question, only now the piano was originally 35 cents flat. 60 cents? 120 cents? Certainly I've restrung pianos and found them pretty sick in a couple of months but have always attributed that to new wire stretch, not tension settling. Helmet on, raincoat on, rubber duckie in hand, I await your missives, if not missiles ...
