I apprenticed under a guy who felt that the C temp was = more forgiving than the A temp. I think he was going to teach me the A = temperament, but he never got around to it and I was too ignorant to = remind him. The upshot is that now that is all I use. I have yet to = tune for anyone other than churches and private individuals. =20 There's really no such thing as "the A temperament", or "the" = F or C temperament. Common practice among most tuners is to set an = equal temperament. What differs among various tuners is the starting = note and the sequence used. The higher up in the scale the temperament, = the faster the intervals beat, though, so if it's hard for you to hear = or "count" the speed of the faster intervals, you might want to set a = temperament lower down at first, like from C3 to C4 or from F3 to F4. = The C to C sequence usually starts with a C Fork, but the F to F or the = A to A sequences usually use an A fork. But one sequence isn't really "harder" or more forgiving than = another -- just located higher or lower in the piano's register. I use the term "sequence" because you're not really setting = different temperaments unless you're intentionally tuning equal = temperament on some pianos, well temperament on others, mean-tone on = others, etc. =20 You could take the temperament sequence you already know, move = it up or down the keyboard, and still set a temperament BUT the beat = speeds of the thirds, sixths, fourths, etc. would be faster or slower. = The three contiguous Major 3rds C3 - E3, E3 - G#3, G#3 - C4 have beat = speeds of about 5, 7, and 9 bps, respectively, whereas the three = contiguous Major 3rds F3 - A3, A3 - C#4, C#4 - F4 beat at about 7, 9, = and 11 or 12 bps, respectively. The 4ths beat ever so slightly faster = and the 5ths almost the same. (Not splitting hairs here, you = tenth-of-a-centers reading this). --David Nereson, RPT, Denver =20 =20 ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
