The concept of centonization (recurrence of melodic formulae) may be expanded to suggest that certain textual elements (including word sounds, placement, and meaning) also may have suggested musical setting. Clues to the sources of these borrowings are sometimes found in verses other than the first one. Whether or not it was conscious, musical borrowing of this type serves to reinforce the authority of the pre-existent material and may be an aid to memory.
