Which step rises in the harmonic scale?

In harmonic minor, the VII level is increased. In this case, an acute gravitation is formed and the increased seventh degree is always resolved into the tonic. Chords that include a raised VII degree (D7 with inversions) are also resolved into the tonic triad and its inversions. At the same time, at the highest level VII, a diminished triad (VII35) and a diminished seventh chord (VII7) are built, which includes two diminished fifths (tritones) and a diminished seventh. This is how a bright and strong gravitation towards the tonic is realized.
