HARMONY. 13* A major chord is also found on the sixth degree of the minorscale. Of the three major chords in C, the first and fourth treatedthus remain within the group, but the fifth passes out of the group,thus :. G, B, D is treated as sixth in B minor. Transition by treating the major chord as sixth in a minor scalemaybe extended by treating the Minor scale as the parallel of a Majorscale, thus: X Tl X 9* ^ ^- ^^^ * f*-fg-f-tefc E g|gg^=B i.
