Yeah, Chris, you keep the oboe in the squaking range for a good bit of that, if not too low. Would work if it were an English horn/cor anglais. Also, aren't the parts usually written on one stave? Flute I and Flute II together, Oboe I and Oboe II together, ect. Is it ever acceptable to divide the parts into separate staves?
Hey, about my chord and what you said... that makes a lot of sense, thank you, QC.
Alrighty... I'm doing Exercise 6 over again, this time with my own and original melody and not some one that I had stuck in my head that turned out to be O Tannenbaum.

This new one is in two separate phrases, melody emphasized in the bass clarinet and bassoons, the rest is support.
I took two tries at it.... my old and weaker attempt is after the first and more successful one, which is my newer attempt with the horns added for resonance. Is there too much movement in the horns? Anything else stick out to you? Comments from anybody are welcome.
