After the first performance in 1808 a first edition and parts were made, but these did not contain some things in the original orchestral parts.
The original set of parts was hardly known about and was found in the Lobkowicz archive in Nelahozeves, Czechia in 1988. This resulted in some errors in the first edition and subsequent editions being researched and rectified.
I have typeset the timpani part as closely as I am able to the original and you can download it here.
With many thanks to the photographers and film makers who have allowed me to use their work; Stephen Tasker, Chris Christodolou (RCM), Tommy Pearson, Monika Rittershaus (Berliner Philharmoniker), Will Schofield, Glyn Matthews, Angus Bremner (SCO) and Zen Grisdale.
