From my music training I knew that some Spanish rhythms apart 5/4 is a time signature used only in the modern era. Holst's Mars from the Planets is 5/4. But if you speak lines of poetry in that pattern you just end up hitting the off-beats. It's only when you add a rest - a sixth beat - that it sounds as it surely should sound.
In a decaying society art if it is truthful must also reflect decay. And unless it wants to break faith with its social function art must show the world as changeable. And help to change it.
