Music Theory Study 5 - Section 1 - Question 3

Hello David,

In Music Theory Study 5 - Section 1 Questions, you answer the Question 3 by saying that the Approach 2 (Ex. 1.8.) and Approach 3 (Ex. 1.10.) are similar and I got a bit confused I guess :

Approach 2 (Ex. 1.8.) : G Major Pentatonic Scale Adding the C for the IV Chord and F# for the V Chord so :

I Chord : G A B D E G

IV Chord : C D E G A B C (6 notes ?)

V Chord : D E F# G A B D (6 notes ?)

Approach 3 (Ex. 1.10.) : Chord Tones of the Major Pentatonic Scales so :

I Chord : G A B D E G

IV Chord : C D E G A C

V Chord : D E F# A B D

So the notes of the approaches 2 and 3 are not exactly the same, is that correct ?

Thanks a lot,

Jérôme
