Re: Oboe Septets
There is a lot out there for trio and quartets where you could simply double,some of the parts. If your professor will play, the only one I know of for that large of a group is "Octandre".
Check trevcomusic.com and then use his search for instrumentation tool to find pieces. I would highly suggest doing trios or quartets with doubled instrumentation...much more available.
