15 hours of the war requiem

So. I'm writting my Mass class paper on Benjamin Britten's War Requiem. And this weekend I'm fairly sure that I've listened to it for over 15 hours. Its a gourgeous piece of music, but it is starting to get a little old.
One of the most interesting features that I've come to apricate is the use of the tritone as a figure of stabilty. Throughout the piece the tritone is usued to establish a key area, which I don't quite understand entirely, but as I listen to this piece more and more the idea is growing on me. The tritone is often presented in a very straightforward manner however at times it is hidden. One such example is one phrase ending on a C# and the next sung one beginning on an F. I really love how it apears so often and in so many varieties.
After listening to this for so long I'm also starting to find myself become more and more liberal and more and more pacifist. I guess Britten knows how to impact people with his music.
