size=2>According to "Music A Mathematical Offering" F-C is tuned perfect, then
divided into 7 equal semitones. Then the rest of the piano is tuned by perfect
fifths from these 8 notes. Can also be seen on Google Books:</FONT></SPAN></DIV>

<DIV><SPAN class=576285120-10012008><FONT face=Arial color=#0000ff size=2>Does
anyone have any experience with Serge Cordier's tuning - Equal Temperament
with Pure Fifths?</FONT></SPAN></DIV>

<DIV><SPAN class=576285120-10012008><FONT face=Arial color=#0000ff size=2>From
my understanding, an equally tempered octave is set (eg. F3-F4) then all
other notes are tuned as pure non-beating fifths from this octave: F4-C5,
F#4-C#5, etc...</FONT></SPAN></DIV>
