Noah, you are absolutely, totally, and in all other ways, correct.<div><br></div><div>I don't know what I was thinking this morning.  Perhaps it was that if you rough in A#3 and D4, you'll have something with which to help you place C#4.  ???  Maybe I should be kept away from email until after 10:00 a.m.  :-)</div> <div><br></div><div>Thanks for pointing this out.  I guess you could call it datum internetum erratum.  Or something.  I'll try to be more awake next time.</div><div><br></div><div>--</div><div>JF<br><br><div class="gmail_quote"> On Tue, Oct 28, 2008 at 10:10 AM, Noah Haverkamp <span dir="ltr"><<a href="mailto:noahhaverkamp@yahoo.com">noahhaverkamp@yahoo.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> <table cellspacing="0" cellpadding="0" border="0"><tbody><tr><td valign="top" style="font:inherit">-snip-<br>Do the contiguous M3s F3-A3, A3-C#4, C#4-F4, and F4-A4.  If you refine your A3-D4 interval, that's a good test for the placement of C#4.  A3-C#4 should beat roughly the same as F3-D4.<br>-endsnip-<br><br>Thats interesting, I've always thought of F3-D4 as being roughly equal to G3-B3. If i remember correctly that's what Randy Potter, or at least a section of his course, taught. Playing all 4 notes together should make, by this account, a pleasant harmony and shifting that chord up a half-step 3 more times is a sort of test for the temperament. i guess it depends on the octave width?<br> <font color="#888888"><br><br>Noah Haverkamp Frere<br><span style="color:rgb(0, 127, 64)">Know-a Piano </span><br><a href="http://www.knowapiano.com" target="_blank">http://www.knowapiano.com</a> <br>347-308-0094 <br>Fax: 718-701-2071</font></td> </tr></tbody></table></blockquote></div><br><br> </div>
