It is still not enough for language to have clarity and content... it must also have a goal and an imperative. Otherwise from language we descend to chatter, from chatter to babble and from babble to confusion.
For me it came from the material. It was so well written and brought the opportunity to work with great actors. And of course the opportunity to 'mince about' was an added element that I wanted to take advantage of!
When I'm alone at home, I really prefer to listen to Wagner's orchestral music rather than any vocal music. I find it illuminating not to have to pay attention to voices in the recordings.
