Of special interest were the echo partitas written by Triebensee with the echo part covered by the second instrument of each pair--with an added contrabassoon part for a total of nine players. Other versions of echo partitas included 12, even 16 players.15
Triebensee's successor as Kapellmeister at the court of Prince Liechtenstein was Wenzel Sedlak, a clarinet virtuoso who died in 1851. Little is known about him, but he is noted here because of his transcription of Beethoven's Fidelio for Harmonie. Of all the authorized transcriptions for publishing, the transcription for harmonie was the fourth completed, appearing in the Wiener Zeitung on January 27, 1815. Beethoven supervised the earlier piano arrangements quite thoroughly, so it is possible that Sedlak also had his blessings on the cuts used in the Harmonie transcription, although the cuts do not coincide with those of the earlier arrangements. Notably most cuts occur during the last third of the opera, when the music is most dramatic. This is possibly due to the perceived unsuitability of certain passages for wind instruments. Some transcribers were in the habit of transcribing everything, down to the recitative, which often lent itself to a less-than-musical rendering for Harmonie, where the original dramatic action could never be fully appreciated
