Well, tho it does exactly that, I think it also is very instructive as to how tuners go about creating the illusion of beatlessness you mention below. And also instructive as to some of the problems we need to overcome to do that. For many, this kind of information, and working ones way through it can be very helpfull. Then too, without this kind of knowledge the SAT, and RCT could not have been invented. > Well that is exactly the task of the piano tuner.

Many ETD users make the mistake of being too "swayed by the graph" as it were. And on the other hand, most every ear tuner I ever met could benifit from a healthy dose of "graph swaying" if you get my meaning. > For me the 2:1, 3:1, 4:1, 5:1, 6:1 should all conform as close > as possible to theoretical.

As long as one is talking isolated coincident partials.... its true for everyone, fact of life... what can I say... the sun will burn you if you get to close to it..... THAT being said... what you say below is also true and is the whole point of our tuning adventure. If the illusion is good enough... then in a very important sense, the octaves are beatless. And regardless of how we tread that path to knowledge..... we still have lots of reason to compare notes and offer each other what we can and what we are in the endeavour to improve, and that so in all humbleness. > But for those who say, "I can offer for your ears a good > illusion of beatless", then we have a lot of notes to compare and > really need to get together from time to time to keep our skills > intact and keep improving. ---ric Cheers RicB -- Richard Brekne RPT, N.P.T.F.
