To determine the effect of inharmonicity on the frequency of the partials, the iH constant is multiplied by the square of the partial number. For a fifth the partial numbers are 3 and 2. The squares are 9 and 4. So iH affects the lower partial of a fifth over twice as much as the upper partial. But for a fourth, the partial numbers are 4 and 3. The squares are 16 and 9. So iH affects the lower partial of a fourth less than twice as much as upper partial. Also a fifth is a larger part of an octave than a fourth. So any stretch done by the tuner will affect a fifth more than a fourth I'm dizzy. Daniel Carlton -------------- next part -------------- An HTML attachment was scrubbed...
