(from Gr. agoge, melody).
1 An adjective indicating a variety of accentuation demanded by the nature of a particular mus. phrase, rather than by the regular metric pulse of the mus. The first note of a phrase, for instance, may be felt to suggest a slight lingering which confers the effect of an accent: similarly, a leap to note significantly higher or lower than the preceding notes, or a strong discord resolving to a concord, may convey an effect of accentuation (by means of lingering, pressure, etc.) and there are other examples. The complementary term to ‘agogic accent’ (accent of movement) is ‘dynamic accent’ (accent of force), which implies the normal and regular rhythmic accentuation of a piece of music.
2 In a wider sense, ‘agogic’ covers everything connected with ‘expression’, e.g. rallentando, accelerando, rubato, pause, accentuation as described above, etc.
