Hence we must put down the quality or timbre as depending on the form.
The substance which determines the form of a column of air is demonstrabl y indifferent for the timbre or quality of tone so long as the sides of the tubes are equally elastic and rigid.
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.
The Scottish timbre is rarely wanting, even in places where scholastic or classical custom might have claimed, as in other literatures, an exclusive privilege.
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.
