Under this same assumption there should be expected in the anapæstic form of rhythm an exaggeration of the progressive increase in the final interval, together with a further reduction in the duration of the initial; since from the falling of the accent on the final interval two factors of increase combine, while in the initial, which immediately follows the accented interval in the series, a positive factor of reduction appears. This is actually the type of change presented by the quantitative relations, which are given as proportional values in the following table.
TABLE XLI.
| Interval | I | II | III | IV | V | VI | VII | VIII | IX | X |
|---|---|---|---|---|---|---|---|---|---|---|
| First, | 1.000 | 0.950 | 1.000 | 0.950 | 1.000 | 0.950 | 1.000 | 1.000 | 1.000 | 1.050 |
| Second, | 1.000 | 1.100 | 1.000 | 1.050 | 1.100 | 1.000 | 1.000 | 1.050 | 1.100 | 1.000 |
| Third, | 1.000 | 1.073 | 1.073 | 1.024 | 1.024 | 1.122 | 1.098 | 1.098 | 1.098 | 1.146 |
Between its first and last terms the first interval shows a departure slightly less than that of the previous rhythm from the rate of change which characterizes the dactylic type; but if the average values of the whole series of intervals be taken in each of the three cases, the progressive reduction will be seen clearly to continue in passing from the second to the third form. The figures annexed give these averages as proportions of the first interval in the series.
TABLE XLII.
| Rhythm. | 1st Interv. | Av. of all others. | |
|---|---|---|---|
| Dactylic, | 1.000 | : | 1.188 |
| Amphibrachic, | 1.000 | : | 1.019 |
| Anapæstic, | 1.000 | : | 1.000 |
The relations of the various intervals in the three forms are put together here for comparison:
TABLE XLIII.
| Rhythm. | 1st Interval. | 2d Interval. | 3d Interval. |
|---|---|---|---|
| Dactylic, | 1.000 : 1.231 | 1.000 : 1.000 | 1.000 : 1.066 |
| Amphibrachic, | 1.000 : 1.045 | 1.000 : 1.000 | 1.000 : 1.054 |
| Anapæstic, | 1.000 : 1.050 | 1.000 : 1.000 | 1.000 : 1.146 |
An analysis of the factors of accentual stress and of position in the rhythmical group in isolation from each other, confirms the assumptions already made as to their influence in defining the form of the rhythmic unit. Table XLIV. exhibits the series of temporal changes taking place in accented and unaccented intervals, respectively, for the three forms combined, and therefore independent of position in the group.
