Do you mean that you play all three of the notes C5, F5 and C6 simultaneously in the left hand and then play C7 and tune it to get a zero beat? This is something I have never come across before, ie playing three notes and beating the partials of them with the note you are tuning, if I interpret that correctly. It sounds very interesting and I will try it out. Thanks a lot!</FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>Robert</FONT></DIV> <BLOCKQUOTE dir=ltr style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="FONT: 10pt arial">----- Original Message ----- </DIV> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: black"><B>From:</B> <A title=jkanter@rollingball.com href="mailto:jkanter@rollingball.com">Jason Kanter</A> </DIV> <DIV style="FONT: 10pt arial"><B>To:</B> <A title=tune4u@earthlink.net href="mailto:tune4u@earthlink.net">tune4u@earthlink.net</A> ; <A title=pianotech@ptg.org href="mailto:pianotech@ptg.org">'Pianotech List'</A> </DIV> <DIV style="FONT: 10pt arial"><B>Sent:</B> Thursday, May 04, 2006 8:29 PM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> RE: Question About Setting Octaves in the High Treble</DIV> <DIV><BR></DIV> <DIV dir=ltr align=left><SPAN class=140372500-05052006><FONT face=Arial color=#0000ff>You want 2:1, 3:1 and 4:1 all to sound good.

The 10th-17th would be the test ... if you could hear it, which, as you say, you can't. So play or ghost the lower note of the octave and listen for zero beats at the pitch of the top note. You may not actually "hear" beats but there is a "sweet spot" that you can learn to hear. All of this, of course, assuming that the top octaves aren't junky with false beats, no clear fundamental (you'd need Tunelab or a spectrum analyzer to see, visually, what this looks like--multiple spikes instead of one, clear 1st partial), excessive hammer noise, etc.</FONT></DIV> <DIV><FONT size=3></FONT> </DIV> <DIV><FONT size=3>Many times, plucking the string with a fingernail makes it easier to hear than striking it with the hammer.</FONT></DIV> <DIV><FONT size=3></FONT> </DIV> <DIV><FONT size=3>Though you say you have trouble hearing 17ths, don't give up on practicing to hear them you will get better at it. For one thing, at high bps you really can't "hear the beat rate" as you put it, but you can perceive faster and slower--almost like you are "feeling" the beats. So don't neglect  your fast-beating tests, i.e., running 17ths.</FONT></DIV> <DIV><FONT size=3></FONT> </DIV> <DIV><FONT size=3>When I was first learning, I thought the bass was easy but that I would never "get" the treble.

Lower down the piano and for an octave or two above the temperament octave I use a 3rd-10th test to check whether the beat rate of the 10th is the same as or slightly faster than the 3rd, to provide an octave that is correctly stretched. When I go higher in pitch I use a 3rd-17th test so that I can still hear the beats and do the comparison. The problem I am having is that when I go still higher, say in the final octave, I can hear the beats of the third but I can't hear the beats of the 17th, or any ripple at all. I can't therefore compare the two beats rates and check the octave. The higher note also dies away quicker so it makes it even more difficult. Is there any special technique I should use to be able to hear the beat rate of the 17th so that I can check the higher octaves? Thank you very much! for your help. </FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Robert Finley</FONT></DIV></FONT></BLOCKQUOTE></BLOCKQUOTE></BODY></HTML>
