Advanced model of keyed bugle: the eleven keys, one for each semitone, extend the compass below the bugle's usual lowest note, B3 by completing the set of twelve fundamentals from B2 up to Bb3. While all played by the same performer, the trumpet, cornet, bugle/flugelhorn are all in different families of brass instruments and all have different sound qualities. For example, the B-flat trumpet, B-flat cornet, and B-flat flugelhorn all have the same range, but the combination of bore structure and mouthpiece depth and design gives these three instruments wholly different characters. The bugle has a conical shape throughout and a funnel-shaped mouthpiece, both of which contribute to the much darker and mellower tone than that of the trumpet. As a result of their deep conical cup and mouthpiece, wide conical bore and relatively flat and sharp rims, keyed bugles produce a rather mellow, ‘wooly’ sound.
