if any, between a symphony orchestra and a philharmonic orchestra, is there a difference in instrumental line up, or is it repertoire? Then there are Concert orchestras, I get the impression that they may tend to play some music other than pure Classical.
Personally I can't say I've noticed a difference.
Bands do seem to be better defined, brass, military, jazz etc, but then there is the Hanover band which is an orchestra.
I didn't find the right solution from the internet.
