So Ive used strings synths before and have written a lot of music using basic string elements in reason. But now that I have GPO 4 I really want to get into more technical aspect of orchestral music and how its composed and what instruments go with each other and dynamics and so on. If some one could recommend me perhaps were there is a tutorial were I can learn these things and also I want to start listening to a lot of orchestral music because I learn a lot from just listening to something and trying to recreate it so if someone could recommend me some music I could listen to thatd be great. I really enjoy sad pieces mostly that are really sad in beautiful way if anyone knows any to be specific but please recommend anything. Thanks again.
