# Preparation of I7 second inversion in minor

The image above (from Korean composer Byung Dong Paik's Theory of Harmonics, page 139) shows progressions 7th chords(I7), and inversion

The book explains that such a process on the second image cannot be done as follows.

"The 7th note in minor loses the function of the leading note and tends to descend. For this reason, it is impossible to proceed with the 7th note as a leading note after preparing it."

It seems to be saying that the leading note from v is not resolved in i34 and becomes the 7th note, so it cannot proceed.

However, there are cases where the 7th is not resolved and stays in place and is resolved in the next chord.

D-F-A-C(ii7) -> E-C-G-C(I6) -> G-D-G-B(V) -> C-E-G-C(I) <-- like this..

As in the case above, the resolution of the 7th can be delayed, but why is it that it is impossible to delay the resolution of leading note?

It focuses on the commonality that notes that need to be resolved can stay and be resolved. So the final question is why C in ii7 (case on the text) can stay and be resolved and B in V (case on the image) cannot?

• What 7th is delayed in your example? The C in the ii7 chord? That's not a leading tone. The B in the V chord? That's not delayed. Commented Aug 13, 2022 at 4:47
• @aaron yes C in the ii7 . and it's not about leading tone. It just meant that in that case it could be delayed, and why the leading tone couldn't be delayed like this. Commented Aug 13, 2022 at 5:00
• Well, first of all, notice that the C still resolves downward, and second of all, there is no leading tone in minor. Commented Aug 13, 2022 at 5:02
• @aaron there is no leading tone in minor. <-- i know! Commented Aug 13, 2022 at 5:04
• @aaron C resolves downward, but delayed i mean Commented Aug 13, 2022 at 5:05
