Each key signature has identical amounts of <BR>dissonance.   All major keys have the same harmonic content, as do the minor <BR>keys,  differing only in their pitch centers. <BR>     Tell them it is a way to erase all the harmonic differences between the <BR>keys, and that it is a tuning perfectly suited to the music composed upon it, <BR>(1900 and later).  Tell them that it is a tuning based on a mathematical <BR>concept, and arose as a result of factory standardization.  It is like off-the-rack <BR>clothing, designed to fit as broad a range of users without being optimum for <BR>any of them. <BR>Regards, <BR><BR>Ed Foote RPT <BR>http://www.uk-piano.org/edfoote/index.html<BR>www.uk-piano.org/edfoote/well_tempered_piano.html<BR></FONT></BLOCKQUOTE></DIV> <DIV></DIV> <DIV> </DIV></FONT></BODY></HTML>
