Substitute Dominant
A substitute dominant is a chord substitution for a chord with a dominant function. Barbara Barry explains:
In the hierarchical organization of key, other degrees may be regarded as having dominant function, for example, the mediant, which can act as a 'second order' dominant, the supertonic, as supportive as a secondary dominant, or the leading note triad. Their ability to define key, though, is less strong than that of the dominant, as is clear when the dominant is present.However, David Epstein disagrees:
... suggest that the mediant served as a 'substitute' dominant. Perhaps so, as a locale for stating subsequent themes. As a substitute tonal function, however, the mediant-as-substitute-dominant theory seems improbable, given the tendencies of tonal behavior. For in major keys the mediant major is twice indirectly removed from the tonic, only three pitches out of seven being common to the two keys.Read more about this topic: Tritone Substitution
Famous quotes containing the words substitute and/or dominant:
“In this loveless everyday life eroticism is a substitute for love.”
—Henri Lefebvre (b. 1901)
“What makes revolutionists is either self-pity, or indignation for the sake of others, or a sympathetic perception of the dominant undercurrent of progress in things. The nature before us is revolutionist from the direct sense of personal worth,... that pride of life, which to the Greek was a heavenly grace.”
—Walter Pater (1839–1894)
