Spectral Enrichment in Valve Trombones

Abstract / Description of output

Following the development of practicable valves in the 1810s, valved versions of horns, trumpets and trombones quickly followed. The valve trombone became a popular and widely used brass instrument throughout the 19th century, although employed less commonly today. Not only were valve trombones made in a great variety of wraps, but also in a wide variety of bore profiles. Many valve trombones were close in bore profile to slide trombones (therefore necessarily close to cylindrical for a high proportion of the sounding length), but some employed novel bore profiles. The range of values of the spectral enrichment parameter E (derived from physical measurements) for tenor valve trombones overlaps with the range of E values for baritone saxhorns. Nevertheless, saxhorns are perceived as cuivres doux (mellow) while valve trombones are cuivres clairs (bright). This anomaly is partly due to different playing styles of valve trombones and baritones, but subtleties in the rates of expansion in bore are also significant. This paper compares these overlapping categories using detailed bore measurements and analysis of playing tests on instruments from the respective families.
