An aspect of the overall meaning of an utterance separated out by Frege (as the Beleuchtung of an utterance). An utterance may be made in a way that is especially apt to affect the feelings of an audience: it may be disquieting, or exciting, or sad, or arousing. Two utterances may thus share their content but differ in tone, if their affective impact is different. Separating the tone from the strict content, for example of a poem, is not straightforward.
