Let say that we want to write a song and, for example, we are using C major scale. In this scale we have: C, D, E, F, G, A, B.

 

My question is, if we want to use for example B in our own song that we write, we can use any variation of this B: B7, Bm, Bm7, Bsus, or only B chord? The same for C, D, etc

Kido, Thanks for the question.  First of all, please join us at the new discussion board at https://www.guitarga...om/community/ 

 

We aren't over at this old discussion board very much anymore.  The new one is where everyone is at.

 

In answer to your question...

 

There are two issues - the NOTES and the CHORDS.

 

For a song or melody in the key of C, you can use any one of the NOTES in the C major scale.  C-D-E-F-G-A-B-C.

 

But for the CHORDS to harmonize with the melody, the chords would be Cmajor, Dm, Em, F, G, Am, Bhalf-diminished

 

I think I get into this around Session 13 of the Learn and Master Guitar Course where we talk about the Harmonized Major Scale.

 

So, it doesn't mean that you only have to use those chords in the key of C but those are the major ones.  So, if you wanted to use some kind of a B chord, you could use a Bhalf-diminished chord or even a G/B (G chord with a B in the Bass)

 

But if you wanted to use a B7, you could still use it - it would just be a passing chord.

 

A possible progression for that would be...

 

C - B7 - Em - Am - Dm - G - C

 

I hope this helps.  And come join us on the other board! - Steve

Thank you Steve for the link and for you good information. So you said

 

Cmajor, Dm, Em, F, G, Am, Bhalf-diminished

 

I was wonder were from you came with the Dm,Em, etc.  I think now I understand, but please correct me if I'm wrong.

 

C (first note):
3rd up = E
5th up = G
Chord = C major

D (second note):
3rd up = F
5th up = A
Chord = D minor (we have a half step between E/F making the minor third)

G (fifth note):
3rd up = B
5th up = D
Chord = G major

A (sixth note):
3rd up = C
5th up = E
Chord = A minor (we have a half step between B/C making the minor third)

B (seventh note):
3rd up = D
5th up = F
Chord = B dim (we have a half step between B/C making the minor third and also half step between E/F, making the minor third)

etc

So on C scale we have

C        D       E    F        G       A       B    C

 whole whole half whole whole whole half

1M     2m     3m  4M    5M     6m   7dim      1

 

Same on D scale, for example:

D       E       F#   G       A       B       C#    D

 whole whole half whole whole whole half

1M     2m     3m  4M    5M     6m   7dim      1

 

So on any scale we have this pattern

 whole whole half whole whole whole half

1M     2m     3m  4M    5M     6m   7m      1

 

 

1, 4, 5 => Major chords

2, 3, 6 => minor chords

7 => diminished chord

 

In lesson 7 where we have that square with all scales, in the bottom we can write:

1M     2m     3m  4M    5M     6m   7m      1

 

If what I wrote is correct, then my question is: where you can use for form (chord)7, (chord)m7, (chord)sus ? Because in your answer you told me that we can squeeze B7 in C scale. How come only B7 and not Bm7 or Bsus, or Bm?

You're doing fine and what you wrote is correct. You're almost there. Each key has its own scale and set of chords, as you've already learned. But the definition of chords is the basic chord, which is a triad (three notes). They're formed from the first, third, and fifth notes of the scale BASED ON THE ROOT NOTE for each triad! But each triad can be modified by adding a seventh. Also each chord can have one of its notes Diminished (lowered by a half-step) or Augmented (raised by a half-step), and if these modified chords have a pleasing sound, they often get  played with the family of chords for that key.

 

If you're really interested in music theory, there's a great book that's long been a favorite of L&MG students: Edly's Music Theory for Practical People. it's written by Ed Roseman and is available online at many places; just Google the title and you can find it. Lotsa luck.

Thank you John Wells. I got the book. I hope I will have time to study, because is not a small book :).
