2.9 - La septième diminuée
- 1:15 : repérages, reconnaissance des septièmes diminuées ;
- 8:40 : la septième diminuée et ses renversements , leur mise en relation avec les états de la septième de dominante ;
- 16:50 : les trois notes à mouvement obligé, leur résolutions ;
- 30:15 : la réalisation de l'accord, son enchaînement à l'accord de tonique ;
- 41:00 : la septième diminuée placée sur la "sensible" de dominante, la notion d'emprunt.

Il ne doit y avoir dans l'écriture deux quintes justes consécutives.
Aller de quinte juste à quinte diminuée n'est pas une faute.
Emprunter est une manière de donner à l'accord un status de tonique. Cela sert à le rendre plus expressif.
