Numerical analysis is a useful tool in determining the relationship between paraphrase and model. This tool is used by numbering the notes of the model. Since the notes of the derived composition use the notes of the model in order, a more detailed map of the relationship between the two is possible. Melodic repetition may be included within structural elongations of pitches. Additionally, the model may undergo transposition. Interpretation of certain passages as transpositions of the model may also help solve certain problems in the application of musica ficta.
