>Ron, >What do you mean by blending impedance? > >Phil Phil, This is referring to the Conklin formula I posted (or something similar) that gives you a relative approximation of the power/loudness/energy a string will supply. Just like we try to avoid big jumps in tension and inharmonicity across transitions from monochord to bichord to trichord, from wrapped to plain, and from bridge to bridge, we don't want audible volume differences at these transitions either. The impedance formula attempts to give us a means to anticipate the approximate power levels across these transitions so we can blend them inaudibly - in theory. It's far from perfect, but it's a whole lot better than nothing. The soundboard, rib scale, and bridge configuration naturally limits what you can do with string scaling. Ron N
