Different vibrational patterns, amplitudes and frequencies , on strings of differing stiffness, have different energies, and these give rise to particle masses via E=mc2.
That's it in a nutshell. If I have time tomorrow, I'll post something a bit more substantial about it, as I have some well-read reference sources to hand that explain it in fairly simple terms with some good references for further reading and some peer-reviewed refs.
Thanks yeah that would be great.
String theory is something that mostly happened after I left physics, and for the last twenty odd years I haven't bothered keeping up, only now am I feeling the urge to catch up ...
