Hello,

Please, I would like to ask if someone could explain or if there are ressources available on the web explaining:

1- the chord substitutions (to M7, 7, min7, sus2, sus4, extended chords, etc.) applied on basic chord progressions in a key (example: why a first chord G should be played as a GM7, the fourth chord C as a Csus4, etc.),
2- the choice of chords which do not belong to the key (example: why a chord that should be played as a minor chord is played as a major chord, etc.),

when composing guitar parts for each of these music genres: blues, pop, rock, hard rock, metal, folk, funk, etc.?

I am asking these two questions because I would like to understand how guitar players selected chords to create the songs that I am learning from Justin's lessons.

Yours sincerely,

Jean

Have you gone through my practical music theory ebook yet? I think that will answer a lot of your questions!

1. See jazz chord substitutions lessons and the jazz chord concept - even if you don't want to play jazz.

2. regarding chord choices out of key - it's just about sound... you can look up secondary dominants or see this lesson on the real ear method!

Hi Justin,

Thank you very much for your answer!

Indeed, I found informations related to my questions at the page 24 of your Practical Music Theory ebook.

I will go after the jazz concepts you mentionned in your answer.

Cheers,

Jean  :)

Also get yourself a circle of Fifths. Adjacent Keys share a lot of the same notes/chords and you can also "walk the circle" and stop at any place.

Just get a circle and google some stuff. Lots of little things the circle can do for getting 'other' chords.

Too much to go into and different people have different little ideas.

Hi TB-AV,

Thanks a lot for your answer!  :)

Indeed, after reading it, I searched and found some sites explaining how using the circle of fifths for chord substitutions:

http://www.angelfire.com/fl4/moneychords/substitutions.html

Etc.

It's probably mentioned on one of those sites but if you recall a popular progression is vi ii V I... Look at your circle.

Pick A for instance... now make that ii or Am. Now just walk CCW A D G C vi ii V I Am Dm G7 C

Also and I got this from a Jazz friend. this is not so much about substitution as maybe modulations. But any time you play a minor chord no matter what it is and what the context.... consider it as though it's a ii chord and carry on from there.

It just leads you down other interesting paths.

Also chromatic movement. Check out notes that are a half step off 'normal'. It is likely it will build a nice chord but it won't necessarily an in key chord.

There is plenty of stuff to do but the really harder part is connecting it all smoothly. So maybe you use the wheel for one idea and some chromatic touches so that things don't move so abruptly.
