Seventh chord inversions

The names of the inversions of the seventh chord come from the intervals that arise between their lower sound, on the one hand, and the base (prima) and top (seventh) of the seventh chord, on the other. In the abbreviated notation of chord inversions, their most important intervals are transmitted using numbers (for example, T6 is the sixth chord of the tonic, V65 is the fifth sixth chord of the dominant, etc.). Diff. the types of inversions of nonchord and undecimaccord are independent. do not have names. See Accord.
