The last week or so I have had my trusty laptop out for some experimentation with TuneLab and it seems like there is quite often a difference between reading a notes partial when played normally, and reading that same partial when playing with the fingernail half-muting the string to accent the partial. Further it seems like the latter is the more accurate of the two. Anyone else ever notice this or have an explanation for this. It seems most prevalent from about 1500 hz upover. The problem also seems to be lessened a bit when muting off the duplex lengths... tho I still can note different readings when half-muting and not. In all cases so far usual play results in a lower frequency then half-muting the same partial. Thoughts ? <<<< After performing some experiments on one string of A4 and measuring the 4th partial (which is over 1500 Hz), I was unable to observe the effect that you mention. In fact, to the limits of the accuracy of the measurement, the 4th partial of A4 when played normally is the same as when half-muting the 1/4 point on the string and plucking with my finger nail. Can you be more specific about your experiments? How many cents difference did you observe? Did the chosen string have any falseness? Were the plucking vs. striking amplitudes similar? -Robert Scott Detroit-Windsor Chapter
