Yes harmonic is sharp, therefore we tune A4 flater. I never said the error was sharp, just that it was a 2.3cent error. The harmonic is sharp, this produces a faster beat rate and we must compensate by lowering the note to slow down the beat rate. The result is a flat note. I descibe the harmonic as 2.3 cents sharp and descibe having to LOWER A4 to compensate for the sharp harmonic by making A4 lower to match beat speeds. What I wrote exactly relating to this is pasted below: I agree it could have been more clear. Sharp harmonic= lowering the note for a flat error ----------------------------- I wrote ---------------------- F3 the beat speed was too fast because we were listening not to the fundamental but the sharper second partial beat, I SLOWED THAT DOWN to match the speed with the beating fork speed. The first harmonic is measurably sharper then the fundamental generates a faster beat speed then the fundamental. We will lower A4 flater by exactly the degree the first harmonic is sharp to slow it down. -------------------------- This is not smoke and mirrors, it is important. Understanding this requires an understanding of what partials and harmonics are, understanding where they coinside, understanding what direction to move the note to speed up or slow down a beat rate. A sharp top note in a 10th produces a beat rate that too fast. We slow down the beat rate to where we want by lowering the top note. The harmonic is sharp, the beat rate is too fast. We slow it down to match beat speeds by lowering the top note, tuning it flat. __________________________________________________________ Find your next car at http://autos.yahoo.ca
