A lilt is a pleasant rise and fall in a voice or a tune. An Irish lilt, a lilting accent, spoke with a lilt.
It is used most of accents — a Welsh or Irish lilt — where it names a musical quality in the intonation rather than the vowels. In music it means a light swinging rhythm. Note that the word is Middle English and its origin beyond that is unknown.
