音程問題(Interval)

以上各題都是6度，例題的C音和A音間有9個半音。
1. C和降A間有8個半音，比major 6th少了1個半音，所以為minor 6th.
2. C和升A間有10個半音，比major 6th多了1個半音，所以為augmented 6th.
3. C和重降A間有7個半音，比minor 6th少了1個半音，所以為diminished 6th.
4. C和重升A間有11個半音，比augmented 6th多了1個半音，所以為doubly-augmented 6th.
5. 升C和重降A間有6個半音，比diminished 6th少了1個半音，所以為doubly-diminished 6th.

Answer
1.minor 6th
2.Augmented 6th
3.diminished 6th
