Hi Terry, That's interesting, thanks for that. The technician I studied with actually didn't go into explanations of such things that I can recall, just said what to listen for and how to tune it. I have to say though, much of my tuning inspiration has come from tuners on various recordings. Such as Rubenstein's 1967 recording of Chopin's Nocturnes - fabulous tuning, excellent sound to the recording as well. I have a debate with myself about whether that or the Werner Haas Debussy recordings for Phillips are my favourite. - John > when the high treble and low bass octaves are tuned "beatless", they > ARE stretched, albeit not to a great degree; in the extreme treble, > because the ear often "hears" even slightly stretched octaves as > "flat", some techs (I know) stretch high C to +75c or more! I don't. > > > Terry Peterson
