The Direction gnrale de lenregistrement, des domasnes et du timbre, comprising a central department and a director and staff of agents in each department, combines the administration of state property (not including forests) with the exaction of registration and stamp duties.
The narrower term "orchestration" is applied to the instrumentation of orchestral music. Since the most obvious differences of timbre are in those of various instruments, the art which blends and contrasts timbre is most easily discussed as the treatment of instruments; but we must use this term with philosophic breadth and allow it to include voices.
As it is with mechanical improvements, so is it to a still greater degree with changes in the function of timbre in art.
The accuracy and the paraphernalia are equally exemplified in all Wagner's additions and alterations of the classical orchestral scheme, for these all consist in completing the families of instruments so that each timbre can be presented pure in complete harmony.
Timbre itself is, as Helmholtz shows, a kind of harmony felt but not heard.
