baritone
or barytone (both: br´tn) (KEY) , male voice, in a lighter and higher range than a bass but lower than a tenor. The term also designates a bass stringed instrument, fretted, with six or seven bowed strings, and up to 20 sympathetic (i.e., unplayed but freely vibrating) strings. Haydn wrote many works for this instrument.
