This goes back to your assumption that this drop probably happens throughout the scale. Pending further evidence to the contrary, I'd tend to conditionally agree (though I don't have any data to support the assumption, I don't see any compelling reason the same phenomenon shouldn't work at all frequencies). <snip> ok guys and gals, We kindof touched on this last year, and were guessing? about sound board/killer octave stuff. The drop does NOT happen evenly throughout the scale, and is measurable. I notice it mostly from about A4 to A6. Easy with a good EDT, just glance at the display and re-adjust as needed on the final pass. Unfortunatly, some guesswork is required as the drop is not even. I really think my work with alternate temperaments has made me more sensitive to micro-adjustments. Every little bit really DOES matter! Since most of the 'challenge' in fitting a tuning to the piano seems to happen below A4, I've taken to starting the final pass around A5 and working my way down, finding the octaves that work best with that piano. The upper framework is in place for checking doubles, etc.. Honestly, some pianos literally walk the razor's edge in what will work and what almost works, (i.e. school Baldwin uprights) while some others give the tuner more latitude to 'create' a tuning. (shameless plug to follow) RCT allows for multiple calculations based on tuning using different partials throughout the piano. I have found that by having a few different tunings calculated, I can switch back and forth between partials, to find a tuning that 'works' for most pianos. This is especially usefull around the tenor/bass break. Other EDT users: Do you pre-check your calculated tuning before you start? I've found it helpful to quickly tune one string of all the A's to get the octave ladder "right" before starting the grunt work. I want them all to 'sing' together and support each other.
