The announcement in the Wiener Zeitung of 22 March 1800 reads: Musical Academy: The undersigned has been permitted to give a grand musical academy in the Imperial Royal National Court Theatre on 28 March.

Haydn’s Trumpet Concerto in E flat was played in the Burgtheater a few days before Beethoven’s first benefit concert-Weidinger’s was on 28 March 1800 and Beethoven’s on 2 April. Although the concerto dates from 1796, it was four years before Weidinger decided to play it in public. Experimental instruments of this kind had previously been known in Weimar and Dresden, but these successful innovations may have prompted Weidinger to develop, between 17, the first fully chromatic trumpet, for which specific instrument Haydn wrote his famous concerto. A second invention (now preserved in the Museum of London) was a silver trumpet, made for King George III’s private orchestra, which had ‘vent’ holes drilled in it: these also improved tuning and gave additional notes. Some English trumpeters were using a mechanical device on their instruments where a retractable tuning slide both corrected imperfect intonation and doubled the number of notes available on the limited scale of the ‘natural’ trumpet. On his return to Vienna there can be little doubt that he informed his friend, the trumpeter Anton Weidinger (1767–1852), of interesting technical developments that he had witnessed whilst in London. Joseph Haydn (1732–1809) first visited London in January 1791, staying in England until June 1792 and even celebrating his sixtieth birthday in the capital.
