I = hope I can word this so it makes sense. It's been a real "stopper" for = me in trusting my aural tuning. I can set A440. I can set a good 4:2 A37 I can fit D42 and E44 in that octave pretty well (match the ETD I check = with) Jim Coleman Sr., Randy Potter, Geo. Defebaugh, and others are pretty = persuasive for using the faster beating intervals (3rds and 6ths) to set = temperament. They all say "Tune F33 from A37 about 7 bps flat ... " and they take off = from there. I like and use Randy's pivot tone thirds, i.e., after tuning = F45, tune C#41 to get an even progression of F33-A37-C#41-F45-A49. = Theory is, if you can get a good progression, you have good A-A and F-F = octaves and a good relationship between those two octaves, i.e., the = F33-A37 third. All of these descriptions of temperament setting use, and I am quoting, = terms like "about 7 bps," "close approximations," "actual beats will = vary from one piano to another," etc. Vague as He**... This is also a quote "While tuning we constantly compare one interval to = another, listening for the sense of the beats, the feel of the beat = speed." I have no problem with any of that and I understand and can actually do = it all. BUT ... HERE THE QUESTION (Looks like several questions, but really asking the = same thing each time ...) How do you really know that your A-A is ideal? That it isn't a smidge = two narrow or wide for the inharmonicity of that particular instrument? = That you have even started the temperament "correctly" for that piano? = How do you KNOW that your F33-A37 is ideal for that particular = instrument? This talk about Franz Mohr, etc., highlights the point: A lot of you = folks can--in your sleep--set a really sweet temperament on any decent = piano you face, Yet the starting intervals seem arbitrarily set, to me! = "About 7 bps ..."=20 So what the heck does "about" mean? Do you have to set the whole T. = before you "know"?=20 (Is this making sense?) I'm not talking about getting just a useful = temperament, as I believe the "about" thing will do that every time. I = am talking about getting a really good temperament for each piano. 'Preciate some comments.
