I have been inspired by this thread and the fugue challenge thread. I've written several little stand-alone fugues, of which I'm happy with 2. I am now going to try to incorporate a fugue into the development of a symphonic movement I'm writing. I do however need some words of advice.
The expo. if myy symphony has so far been an unashamed attempt to clone Mozart. I am also using a small orchestra, 2 flutes, 2 horns +strings. Here are my questions:
1. Should I do an actual fugue or is a fugue-like (fugato) section more appropriate?
2. If I write a fugue, should it necessarily be 4 or more voices as opposed to 3 voice?
3. Should I use the entire orchestra by doubling voices?
4. If the voices are doubled, should they go violin I+flute 1, Viloin II+Fl. 2, etc or Violins I+II, Fl 1+2?
5. Would it be appropriate to attempt a double fugue in which the first subject uses either strings or winds and the other subject uses the other group?
6. Any other suggestions?

I'm more than willing to experiment, but my fugue writing attempts so far have been VERY time consuming, and I'd rather not waste my time trying a "stupid" approach.
I welcome any comments. Thank you.
