Chord relation in major scale

So I went to the lesson in rock level 2 : chords relation to major scale and the instructor thought that the chords 2,3 and 6 are flat but aren't they suppose to be just in a minor forms as I learned before ?

I'm not sure which lesson you are referring to in rock 2. But, yes the ii, iii & vi chords are minor chords. Maybe Anders was referring to the minor 3rd of each chord being flat compared to it's major chord counterpart?

I cover major scale harmony in depth & detail in this tutorial.

Thanks for the link. Anders is describing modulations, which are chords outside of the key signature.

So, he's building chords on notes that are not a natural part of the scale he's starting with. As he says they are "outside". This is used in all styles of music. He's showing you some of the common ways this is done in rock styles.

We start by learning the idea of a key signature & staying in that key because it's the default setting. Then we can learn examples that are exceptions or outside of the default setting. In fact, that's where much music gets it's interesting & spicy sections & sounds!

In this example, Anders starts in the key of A major, so that's our reference point. However, the note C is not in the key of A major, but you can still use it. And you can label it by observing the C is the minor 3rd, or flat 3rd relative to A, so we label it with a flat sign. It's a major chord so we use upper case Roman Numerals.

A (I) > C (bIII) > A (I) > Bb (bII)[br][br]If the C major chord was a minor chord in this example, then you would use lower case Roman Numerals.

A (I) > Cmin (biii) > A (I) > Bb (bII)

In short, you can use any chromatic note & build any chord. You use the interval distance from the root note to identify & label it. Possible examples including chords in & out of the key signature of A major.

A major (I)

Bb (bII)[br]Bb minor (bii)

B minor (ii) - in key

B major (II)

C minor (biii)

C major (bIII)

C# minor (iii) - in key

C# major (III)

D minor (iv)

D major (V) - in key

D# minor (#iv)

D# major (#iv)

E minor (v)

E major (V) - in key

F minor (bvi)

F major (bVI)

F# minor (vi) - in key

F# major (VI)

G minor (bvii)

G major (bVII)

G# dim (vii dim) - in key

G# minor (vii)

G# major (VII)

Hope that helps!
