The key of the month club is going well. I've composed three songs in the key of B. Even if this experiment lasts only one month, it will have been worthwhile. Even after only a week B is no longer one of my weakest keys. Thinking in terms of sharps rather than flats reorients my vision, so that Eb - 7 becomes D#-7.
A melodic "hook" has the shape of a hook, on the axes of pitch and time.
