Trom"bone (?), n. [It., aug. of tromba a trumpet: cf. F. trombone. See
Trump a trumpet.] 1. (Mus.) A powerful brass instrument of the trumpet
kind, thought by some to be the ancient sackbut, consisting of a tube
in three parts, bent twice upon itself and ending in a bell. The middle
part, bent double, slips into the outer parts, as in a telescope, so
that by change of the vibrating length any tone within the compass of
the instrument (which may be bass or tenor or alto or even, in rare
instances, soprano) is commanded. It is the only member of the family
of wind instruments whose scale, both diatonic and chromatic, is
complete without the aid of keys or pistons, and which can slide from
note to note as smoothly as the human voice or a violin. Softly blown,
it has a rich and mellow sound, which becomes harsh and blatant when
the tones are forced; used with discretion, its effect is often solemn
and majestic.
