Comments:
| Measure | Rectus | Inversus | Transformations |
|---|---|---|---|
| 24 | G minor chord followed C minor's vii degree | A minor chord followed by what appears to be a G minor's dominant chord | G <--> E D <--> A B <--> C F <--> F |
| 25 | C minor, Bb major's ii degree | It first looks like G major, but it's an E minor chord in first inversion | C <--> B E <--> G |
| 26 | Bb major V degree followed by vii | B minor chord (the harmonic function is not clear), followed by A minor's dominant chord | F <--> F C <--> B A <--> D |
| 27 | G minor chord, followed by Eb major's vii degree. Eb major is Bb major's IV degree | A minor chord, F major's iii degree | G <--> E D <--> A B <--> C |
| 28 | Bb major's IV and V degree chords | F major's vii degree | E <--> G D <--> A B <--> C |
| 29 | Bb major key | F major key | B <--> C D <--> A |
