Hello all. In a recent thread we touched on the topic of what is appropriate in cadenzas in conciertos written for instruments different from those that we generally play today...i.e.-Haydn for keyed bugle and the baroque literature on natural trumpet. So my question is: How far do we take this? aside from solo playing, we also play a lot of the germanic rep. on rotaries...but not all. How much historically/stylistically performed performance practice can we incorporate into the modern symphony orchestra? I remember hearing Doug Yeo of the BSO play a Rossini overture on oficlide. It was very nice, but is the BSO the right place for it? Another example would be the Mahler Chamber Orchestra doing Beethoven 6 with Natural trumpets and everyone else on modern instruments. Without stating any of my opinions, anyone have any of their own?
