I put a message in the Listening Room suggesting that it may be better to make another Subject Page (or whatever you call it in technical terms), where people can discuss the various techniques NOT concerning the ones we already have, e.g. composition techniques, rendering techniques, etc.
Think it over, please.
Last month I ordered at Amazon some orchestration books. They didn't arrive and I asked Amazon where they were lost or else. Amazon investigated the order and told me that the package was lost "somewhere in space" and promised me to send the same books once again. To my surprise I've got BOTH packages on the same day.
I told Amazon about this strange thing and told them that I was willing to send one of the packages back. Their reply was that it wasn't worth the effort and suggested that I could give it away.
The Technique of Orchestration, 6th edition, by K.Kennan and D.Grantham including a samples CD of the examples used
Essential Dictionary of Orchestration [this is some sort of a lexicon explaining in short the character of the instruments, ranges, weak and strong register, etc.]
I am willing to send it to you, or to destine those books to whoever in your Forum. Let us say: some sort of competition and then NOT the winner because he/she doesn't need it or whatever you like.
Now those books are just collecting dust.
