<div>John:</div> <div> </div> <div>I have given my P4-P5 octave test some careful critiquing and have decided that I am listening to the 6:4 5th beat speed and not the 3:2 beat speed. The octave width seems to be about 6:3 and not 4:2 when using the faster beating tests. I like the sound of the resulting octave very much.</div> <div> </div> <div>Can you explain how the A3-E4 and E4-A4 beat speeds are equal in a 4:2 octave?<br></div> <div class="gmail_quote">On Tue, Oct 28, 2008 at 9:17 AM, John Formsma <span dir="ltr"><<a href="mailto:formsma@gmail.com">formsma@gmail.com</a>></span> wrote:<br> <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid"> <div class="gmail_quote"> <div class="Ih2E3d"><Snip><br></div></div> <div>Tune A4, then A3. Quickly tune D4 and E4 to see what kind of octave there is (and also to "rough in" D4 and E4).  Just get those two test notes close.  Remember that a 4:2 A3-A4 octave will produce equal beating from A3-D4 and D4-A4 (also A3-E4 and E4-A4).</div> <div><br></div> <div><Snip><br></div>-- <br><font color="#888888">JF</font></blockquote> <div> </div> <div>-- <br>Regards, <br>Jeff <span class="goog-spellcheck-word" style="BACKGROUND: yellow">Deutschle</span><br><br>Please address replies to the List.
