Sorry that I gave the impression that that I "tune" spokes to exact pitch. I only use it to bring spokes to the same relative tension. Spokes of same length/material and tension will produce the same pitch (more or less). Two guitar strings both being equal in every way when tensioned the same will produce the same pitch. Given that, spokes of similar dimension and material should produce the same pitch when brought to the same tension you can use the pitch method as a tool for even tensioning. So all drive side spokes when bought to the same tension will be one pitch all non-drive side brought to the same tension will be one pitch...but not the same pitch. There is no one perfect pitch that is appropriate for all cases as length of spoke is an important variable. Different lengths will produce different resonant frequencies due to the shortening or lengthening of sine wave when the spoke is plucked and vibrates. Back to old and new's point, it's true you don't tune a guitar to LINEAR tension to achieve a certain pitch however, if you know that a certain pitch produced on the guitar string will yield a certain tension you can achieve that tension by producing that pitch. The flaw being that guitar strings stretch over time and one of your variables change because of it (string's vibration characteristics). A spoke does not stretch nearly as much as a guitar string so pitch to tension relation stays true much longer. Now, you cannot create a true wheel on pitch tension alone. You simply use it to achieve even spoke tension then visual truing will be needed. Pitch will only allow you even tension that is neither too high or too low. By the way, if you want more specifics, I'll gladly take off my music man hat and place on my engineer hat just for you.
