While David Andersen is a fellow I've understood deserves all the respect in the world, and he certainly gets it from me, I have to distance myself from this whole approach to advising new students. Partial matching seems more and more to me to be a very misunderstood affair. Its like most folks simply reduce the whole idea to a simple easy to follow recipe and dont really want to get the bigger puzzle clear in their minds. It seems no better in ETD users who apparently all to often simply choose a given octave stretch without really understanding what it results in beyond some very stretch issues citing simply that said stretch "sounds best", offering no further qualifiers. Partial matching in itself is simply a tool. Understanding the tonal results of various partials alignments from a holistic perspective is a rather daunting task, and its easy to get crossed up many times along the road.... but there is nothing about that that in the end is at odds with the Virgil Smith philosophy of tuning. For that matter establishing any kind of piano <<tone>> (in the sense Andre uses the word) can be as easily accomplished by conscious and informed use of partial matching tools. The nice thing about partial matching is that the approach lends itself very easily to clear concise explanations that are easily understood and learned. It also lends itself well to developing and understanding of the tuning puzzle that in turn can find its end in one or another holistic perspective like Davids above. One other point... there simply is no such thing (within a quite wide set of parameters really) as a bass that is too sharp or too flat... too stretched or not stretched enough. Acceptable beat rates for the 4:2 in the lowest bass area range from 2 bps wide to even a bit narrow given the many many articles and treatises written on the subject. The amount of stretch is in itself a purely subjective matter. The only real criteria for <<correctness>> or <<quality>> is how well the tuner understand what they are trying to accomplish, and how well they succeed in executing those. Cheers RicB
