historical usage of sequence

The original meaning of sequence in Middle English was “a hymn sung after the gradual and before the gospel during Mass.” The Middle English noun comes from Old French sequence, whose original sense, dating from the second half of the 12th century, was the same as in Middle English. Old French sequence comes from Medieval Latin sequentia, with the same original meaning.
Sequentia is a feminine noun formed from sequēns (inflectional stem sequent- ), the present participle of the verb sequī “to follow,” and the noun suffix -ia . A sequentia was so called because it followed the Alleluia (a liturgical chant in which the word Alleluia (Hallelujah) is combined with scriptural verses, usually from the Psalms).
The usual, typical sense of sequence, “the succession of one thing after another,” first appears in 1575.
