Abstract / Description of output

Narrow-bore instruments are commonly perceived to be brighter than wide-bore models of the same kind of instrument. This effect is closely related to the effect of the bore profile of a brass instrument on the potential for non-linear propagation of sound within the tube. This paper reports on practical tests with trumpets of different bore diameters, experiments with loudspeaker excitation of instruments, and simulations. The brassiness curves of instruments with similar Brassiness Potential but differing in their absolute bore diameters are compared. The relative importance of the two effects is explored.
