Joseph Haydn’s (1732-1809) “Trumpet Concerto in E flat” was written in 1796, a work in his later years, the last work in his life as well. It was written for his friend Anton Weidinger(1766-1852), an Austrian trumpet virtuoso.Weidinger improved a nature trumpet by adding holes and five keys, which made it able to play harmonic or chromatic notes, other than those only in A or D scales.This improvement had been touching discussions among musicians. The concerto had been disappeared from sight until discovered and published 100 years later, when people realized “Trumpet Concerto in E flat” is so significant in the history of trumpets.

Weidinger’s improved trumpet conduced to Haydn’s “Trumpet Concerto in E flat”, and again later Johann Nepomuk Hummel’s (1778-1837) Trumpet Concerto in E major. Haydn’s and Hummel’s Trumpet Concertos are both ones of common scales in competitions, orchestra exams and concerts.Weidinger’s improved trumpet is replaced with current one at last. Howerver, keyed trumpets and works are still valuable in history of trumpets.
