I heard today parts of the Bach Christmas Oratorio on the radio. The trumpets were perfect. Gorgeous playing. They played on baroque trumpets, no doubt about it. You can't mistake the unique sound, trills etc. The rythm was energetic, about 1/8 = 135-140 so in my opinion these specific trumpet parts had to be double tongued. Maybe it could be done by single tonguing after rigorous training but I think it's very unlikely and not practical. In his book Arban tells that he was the first cornet player to use the double / triple tonguing which untill then the flute players were using. I wonder, could it be that these baroque pieces were originally played at a much slower tempo or could it be that trumpeters such as the famous Reiche did use double tonguing and this ability was later lost? What are your opinions? it would be interesting to hear opinions from players here who do play on baroque and natural trumpets, such a Rowuk. This brings to mind, what is the opinion about it in Germany? Did Edward Tarr ever discuss this?
