Shimming, or =B3cracking=B2 unisons, is something Virgil Smith has talked about for many years. I=B9ve also had an in-depth conversation about it with Eric Schandall, a true wizard from the Steinway basement---he uses it every time he tunes. Shimming is changing the pitch extremely slightly of the right string of a unison, and then bringing the other two strings in unison with the right. With some practice, your temperament becomes super, super precise; more tha= n you thought possible. The possibility of executing super small pitch moves to idealize your temperament has been a very powerful focusing device for me; it=B9s allowed me to make what I call an ideal temperament for that piano in between 20 and 30 minutes---and the temperament is SOCKED in solid. >From it, you can trust without reservation that you=B9re replicating the note relationships within the temperament over the entire compass of the piano---with the proper stretch, of course. In my system, following those slowly rolling fourths down to A0 is my automatic stretch calculator in the bass; after A5 or so, I switch from checking with fourths to checking with double and triple octaves, and sometimes with 11ths and 18ths, which should act like fourths---slowly rolling. I WILL send a version of my tuning pattern and protocol; I wrote it back 3-= 4 months ago, and then Virgil had an article in the Journal, and I guess I felt intimidated---but what the heck; I=B9ll send it soon---after some more little editing and tweaking.
