The basic funda of chords(as Vini kindly put it) :
Each note of the major scale corresponds to a chord. Seven notes=seven chords.
1st note- The root of the scale. Major chord.
2nd note- Minor chord
3rd note- Minor chord
4th note- Major chord
5th note- Dominant seventh chord. May also be played as a major chord but the family remains dominant seventh
6th note- Relative minor. minor chord. The natural minor scale of this note is the same as the major scale we are talking about right now.
7th note- Half Diminished chord or Minor7th flat5th. Not a lot of guys mess with this.
So for the C scale-
Notes: C D E F G A B
Chords- C Dm Em F G7 Am Bm7b5
Relative minor- A
Am scale- A B C D E F G
