t u n i n g [day-night]

  Tune up (your vehicle), tuning up (your instruments), tune in (to radio waves, to a station). Tuning is what usually happens before the 'real' performance, before the possibility of 'getting it right'. It's what one does to extract the best possible performance from an array of components that together may become something. It's not a new analogy for writing, for thinking, for making, yet it suits my purposes well for working out what the question is, or, as Henri Bergson says, how to ask the question using the correct terms.
