Back then Sanderson included ten free charts loaded into the first 10 = pages. These charts were handy when first learning how to use the SAT. To make = sure the charts were not accidently lost I decided to copy them on paper. I then = noticed Sanderson had used unusual partials to record the note cents numbers. </FONT></DIV> <DIV> </DIV> <DIV><FONT size=2>Normally we would tune notes A0 up to B2 as a 6:3 = octave so the note A0 cents number would be recorded at partial E3. Sanderson had = recorded the A0 at partial A2. The other notes up to F6 also were recorded at = different partials than we use today or those used by FAC. Well this confused me = and I remember calling Al Sanderson about this. </FONT></DIV> <DIV> </DIV> <DIV><FONT size=2>I don't remember his explanation but it's obvious = the charts were accurate, just recorded at different partials. He must have tuned = note A0 as a 6:3 octave at partial E3, then dropped down to partial A2, stopped = the lights and stored the cents. At E3 the cents for note A0 might be = (-18.3) but at A2 the cents would be lower at maybe (-24.5).</FONT></DIV> <DIV> </DIV> <DIV><FONT size=2>Using the charts was no problem <U>but I always = wondered why the partials were stored that way. </U>One of the = charts was the Steinway D. The 1989 SAT manual on Page A16 even has a sample form = with these unusual partials.</FONT></DIV> <DIV> </DIV> <DIV><FONT size=2>In 1996 I updated to FAC and don't used charts that much anymore. Eventually you learn how to make your own charts (if = you have the time). </FONT></DIV> <DIV> </DIV> <DIV><FONT size=2>Sy Zabrocki</FONT></DIV> <DIV><FONT size=2>Billings, MT</FONT></DIV></BODY></HTML>
