Now, when one is tuning a stringed instrument, one listens carefully to a transient resonance and how it ‘warbles’ between the source and string as one adjusts the -tension- on the string. Tuning = tone = tension over distance. What I want to highlight is this: the tone ‘warbling’ that happens as we tune strings? It happens to us. At night. When we fall ‘asleep’. No one ever examines this word.
