Tromboni

The most convenient and natural order is, perhaps, the following: the upper staff may have the flute-part, because it has the highest notes, and, therefore, requires most room above the staff; then follow the parts for the hautboys, clarinets, horns, bassoons, tromboni, trumpets, and drums; the upper half of the page thus containing the wind-instruments: the lower half belongs to the violins, viola, voices, violoncello, and double base.

The tromboni, trumpets, and ophecleidi carried every thing before them.

But while the voices have immovable material, the groups of instruments, composing an orchestra of cornetti, viols in various sizes, and tromboni, present a sharp contrast.
