Listening for a Change in Tone

Across a long interview, a subject's voice settles into a kind of baseline: a typical pace, a typical warmth or reserve. A sudden departure from that baseline, a voice that tightens or quickens on one particular topic, is often more informative than the literal content of what is said at that moment.

Catching this requires holding the earlier part of the conversation in memory rather than treating each answer in isolation. It is a cumulative form of listening, built across the whole sitting rather than exercised moment to moment, and it tends to improve with sustained practice over many interviews.

A noticed shift in tone is best treated as an invitation to ask more, gently, rather than as proof of anything on its own. The tone flags where attention might be worth spending; it rarely tells the whole story by itself. It marks where attention might be worth spending, without ever settling the matter entirely on its own.
