Piano reduction in E major and E flat major with parts in E/E flat C and B flatHummel's Trumpet Concerto is still one of the most popular concertos for this instrument. He composed it in 1803 for the Viennese courttrumpeter Anton Waidinger whose newly developed key-trumpet enabled him to play in a much more virtuoso manner than on the traditional natural trumpet. Henle's Urtext edition reproduces the work in the original key of E majorwith solo parts in E and for the more common trumpet in C. Due to the fact that the concerto is nowadays often performed in E flat major this edition also contains a piano reduction in E flat major for trumpets in E flat and Bflat. The different transpositions are now available in one single edition for the first time.
