I think it's bit of a shame that the time dependence is left as a footnote. ADSR envelope and other expressive dynamics have also huge influence on the perceived sound of different instruments (for at least me..). This has been then explored by electronic musicians by mixing and matching the dynamics and overtone patterns to create all sorts of interesting novel sounds.
