Origin & History of “tune”
Tune originated as a variant of tone, and to begin with it was used for ‘sound, tone’ (‘He told him of the death of Brunes; then were made hideous tunes of many a gentle damsel’, Troy book 1400). very quickly, however, the sense ‘melody’ emerged (it is not present in tone), and eventually took over from ‘sound’. The derivative attune dates from the late 16th century.
