Well, I cannot answer your question (and there is no such thing as a stupid question, ..., there are only stupid answers..., I hope this is not one of those... ;-) But this is the (JavaScrip) formula my calculator uses for the tension: T = (F*L*D)*(F*L*D)*(3.14159265*P/(9.81*1000000*1000000)) T = Tension F = Frequency L = String Length P = String diameter D = Density of String material I got this formula years ago from a harpsichord maker... And I am a "computer scientist", I do not know too much of the physical world... ;-) Arto
