yes, I find that on pitch raises on a small error, the bass strings in particular below the tenor break have?little if any effect on the stability of the middle section. So I do the?bass section last in those cases. The last treble octave is different. If I know the piano, and the top octave is close to pitch; I'll wait till the last pass to get to it.? Out here in Colorado, the pianos can go up 20 cents in 2 weeks during the summers.

Is this a common shortcut? Leaving off the copper-wound and the top octave on raises less than a certain value (in this case, 10 cents)? That would definitely be a time saver as long as it didn't sacrifice the stability of the final tuning. I'm assuming you get good results, Bruce?? ? Or maybe I'm reading it differently... Do you make this first pass on the middle sections as a precursor to your tuning when a pitch raise isn't needed?? ? Thanks,? ? Rob? ?
