The Total number of pre-fourteenth century lais published with music is twenty-six, of which the greater part, seventeen, may be found in the valuable Chansonnier Noailles. The Provençal lais were usually called descorts, of which Jeanroy has traced twenty-three, though only two of these are provided with music and one is incomplete. Various views have been put forward as to the meaning of the word descort, but as with so many medieval terms the meaning seems to remain general. Descort means disagreement of any kind, and this may apply to contrast between the mood of poetry and music, to diversity of poetic and musical structure, or some dispute in the text, and to any difference between the music of the descort and that of other forms, etc.
