There is no perfect octave <DIV></DIV>tuning - one must choose which partials one will use. For example, C1 and C2 <DIV></DIV>have common partials at C2, C3, G3, C4, E4, G4, C5 etc. and it is not <DIV></DIV>possible, as far as I know, for any two of these partials to both be tuned <DIV></DIV>perfectly in the octave. If you are listening to the C2 partial, you are <DIV></DIV>tuning 2:1 octaves, if you are listening to C3 you are setting 4:2 octaves, <DIV></DIV>G3 - 6:3 octaves, C4 - 8:2 octaves (unlikely) etc. <DIV></DIV>It would be good for you to identify which octave type you prefer by finding <DIV></DIV>out which tests validate the octaves you prefer. <DIV></DIV> <DIV></DIV>||  |||  ||  |||  ||  |||  ||  |||  ||  |||  ||  |||  ||  |||  ||  ||| <DIV></DIV>jason kanter . piano tuning/regulation/repair <DIV></DIV>bellevue, wa . 425 562 4127 . cell 425 831 1561 <DIV></DIV>orcas island . 360 376 2799 <DIV></DIV>----- Original Message ----- <DIV></DIV>From: "Bec and John" <bjsilva001@comcast.net> <DIV></DIV>To: "Pianotech" <pianotech@ptg.org> <DIV></DIV>Sent: Wednesday, June 09, 2004 7:38 PM <DIV></DIV>Subject: Tuning styles with octaves <DIV></DIV> <DIV></DIV> <DIV></DIV>> Hello, <DIV></DIV>> <DIV></DIV>> I am curious about people who do not tune octaves "perfectly". For <DIV></DIV>> instance, tuning bass notes flat or sharp in smaller pianos in favour <DIV></DIV>> of better partials. <DIV></DIV>> <DIV></DIV>> My own taste and philosophy is to tune all octaves completely <DIV></DIV>> beat-less. Even in the bass of small grands, if the note is off-tune in <DIV></DIV>> favour of a potentially less offending partial that will bother me far <DIV></DIV>> more than the partial. In the highest range, beats appear with the <DIV></DIV>> smallest of imperfections and, to me, perfectly clean higher notes (at <DIV></DIV>> least on a nice piano) are so pretty - even a very slow beat ruins it <DIV></DIV>> for me. <DIV></DIV>> <DIV></DIV>> So I was curious to hear people's explanations for stretching octaves. <DIV></DIV>> I always figured it was to humour the person they are tuning for, <DIV></DIV>> although I have gathered from postings on the list that some tuners <DIV></DIV>> prefer it themselves. <DIV></DIV>> <DIV></DIV>> When I was studying tuning I recall reading or hearing someone say that <DIV></DIV>> if the octaves were tuned "perfectly" they'd be off tune at either end <DIV></DIV>> of the piano - I found exactly the opposite! :) <DIV></DIV>> <DIV></DIV>> Thanks. <DIV></DIV>> <DIV></DIV>> - John <DIV></DIV>> <DIV></DIV>> _______________________________________________ <DIV></DIV>> pianotech list info: https://www.moypiano.com/resources/#archives <DIV></DIV>> <DIV></DIV> <DIV></DIV> <DIV></DIV>_______________________________________________ <DIV></DIV>pianotech list info: https://www.moypiano.com/resources/#archives <DIV></DIV></div><br clear=all><hr> <a href="http://g.msn.com/8HMBENUS/2743??PS=47575">Check out the coupons and bargains on MSN Offers!</a> </html>
