Before I ask the question, sorry that the title is so long. If somebody could shorten it while still getting across what I am asking about, that would be nice. On to the question itself.
So, I have this question that might possibly be on topic for the main site. I have already asked it in the chat just in case it isn't on topic for the main site. The question has to do with whether or not a specific passage I composed for the flute in a duet piece of mine is possible to play at fortissimo given the Presto tempo or whether it is too low and I should raise it up an octave.
