A

Extending 7th chords in 3rds without repetitions

1 3 5 7 9 11 13

1 3 5 7

21

What are chord tensions

A

9 11 13

22
Q

What are secondary dominant chords

A

Borrowed chords from the key that you are trying to resolve or move to.

They use they ket of the target chord to find the notes of the secondary dominant.

23
Q

Which tensions can be used in secondary dominants?

A

9

b9

b 13

24
Q

What do secondary dominants resolve up to?

A

They resolve up a perfect 4th to a diatonic chord

25
Q

How are secondary dominant chords written (C)

A

V7/ II = (A7 in key of C)
V7/ III = (B7 in key of C)
V7/ IV = (C7 in key of C)

and so on

26
Q

What are extended (sequential) dominant chords?

A

They are chords that move up in 4ths, dominant chords with roots that are diatonic. Only the first and last chords need to be analysed.

27
Q

What are substitute dominant chords?

A

They are dominant chords with roots that are diatonic and resolve a half step down.

28
Q

How are substitute dominant chords written (C)

A

Sub v7 = (Db7 in key of C major)

Sub V7/ II = (Eb7 in key of C major)

Sub V7/ IV = (Gb7 in key of C major)

and so on

What is a modulation?

A

When songs move from one key or tonal centre to another for a section e.g a bridge or longer passage

39
Q

What is modal interchange?

A

When songs incorporate shorter passages where chords are borrowed from another key

Q

What are diminished structures commonly seen as?

A

Passing chords, and may also have an auxiliary function i
