No, but...
... it would be rad to have a bike-frame (forks would work better) glockenspiel!

Long as it don't B-flat..........
you can affect the frequency harmonics by drilling holes in the frame tubes.
that'd certainly affect the ride characteristics.
but yes, you CAN "tune" frame tubes with cables under high tension running through or attached to the tube, trimble did it a long time ago (IIRC), and motoczyzs (sp?) wanted to do it with their swingarms as recently as last year (again, IIRC)
what you're doing is pre-flexing the tube in a specific way, like pre-loading a spring, to induce (hopefully) favorable flex characteristics.
the structure probably WOULD have an altered pitch. because it would reverberate only with the cable and less against it, thereby altering the distance the frametube is travelling to achieve it's harmonic.
at least I think it would.
you owe me a double double extra large and two ibuprofens for that one.
