Alan Barnard Salem, Missouri ----- Original Message ----- From: Cy Shuster To: Pianotech Sent: 12/20/2005 4:24:36 PM Subject: Re: How to explain a pitch adjustment I measure pitch on all the A's before I start, and record this for the customer on a graph on the invoice. This gives them a great visual about what work is needed. The graph indicates "fine tuning" range (+/1 eight cents for me). The analogy I use is sanding: if wood is very rough, you can't start with the 1000-grit paper; multiple passes are required. Same thing for painting: with regular maintenance, one coat covers, otherwise you may need several. A description of the forces involved helps: 15 to 20 tons of tension overall; a pitch raise can add a ton of tension (right?), yet a fine tuning requires < 1% accuracy. No wonder it doesn't last! --Cy-- ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
