Farber: Inspiration is such a fickle vamp. Without a warning she'll come for you, a melody right in the eye of the mind. You rush to your instruments--it should be easy. The music should surge through your instruments like the blood through your veins. But it's always painful instead, isn't it? You work it and work it, trying to get it down. Trying desperately to capture that vanishing moment the muse loaned you only a split second ago.
