Hi, thanks for the observation. The instrumentation is a hybrid between classical and romantic, so the choice of 2 horns was intentional; regarding the single oboe, originally I wanted to write a second part for the english horn but this proved unnecessary - I guess the 2nd oboe will go for a smoke during this movement :) Or, I might redistribute the voicing among all the woodwinds. I should have specified the instrumentation more clearly at the beginning of the score, thank you for bringing this issue to my attention.
I will try to come up with a cleaner score as soon as I can.
