an important moment in the first movement occurs in measure 109 (and repeats in the recapitulation in measure 327). in these measures, schubert holds a tonic b pedal in the second bassoon and first horn under the dominant f chord, that evokes the end of the development in beethoven's "eroica" symphony. unfortunately, a well-meaning but inexperienced editor removed this dissonance by altering the second bassoon and first horn part. conductors must check these parts carefully to make sure that the b pedal is intact.
