The chord built on the seventh degree of the scale is a diminished chord.Įven among the chords that naturally occur in a key signature, some are much more likely to be used than others. The chords built on the second, third, and sixth degrees of the scale are always minor chords (ii, iii, and vi). The chords built on the first, fourth, and fifth degrees of the scale are always major chords (I, IV, and V).
