In David Zinman's complete Beethoven symphonies with the Tonhalle orchestra, he uses the Barenreiter edition, modern instrument, and fast tempos.
In his performance the first movement of the 2d symphony, there are a number of prominent stopped horn notes. They are not marked stopped in any score I have access to and I have not heard these note played stopped before.
I do not have access to the Barenreiter score.
Does anyone know where these stopped note come from? Barenreiter? Possibly notes that would have to be played stopped on a natural horn?
In response to comment:
Using the Dover score (available at IMSLP):
2d page, 1st system, 3d measure: F 3d page, 1st system, 1st measure: F 3d page, 2d system, 2d measure: F
3d page 2d system, 3d measure: F/G unstopped
