It is = now in storage in Florida awaiting sale. This pianoprovided me with a = standard of false beat EXCELLENCE, and was my basis of comparison with = my own first restringing job.The M&H had only a couple of 8th octave = strings which had hints of false beats. All else was essentially false = beatless. Good Job Chris, if you are listening. My own Yamaha DC2 is = pretty close to that, but not that good. Phil Bondi tells me that the = Baldwin grand which I helped him restring was also pretty close to false = beatless in the upper octaves. So, from my limited experience, I would = have to vote for trying for NO false beats. Reality, however, will = probably humble me again yet this evening when I get back to my own = restringing project.

When tuning pianos in the field, blending is utilized = by me quite often to mask inherent discrepancies that will never be = properly addressed. =20 These are my thoughts on the matter, Dave, on chasing down the worst = offending false beat situation. =20 Rest easy in this matter.
