The notes in the A Major scale are:
A-B-C#-D-E-F#-G#. From here we will make 7 chords in the Key of A. To do this we will take the 1st note (A), skip the next note (B), take the next note (C#), skip the next note (D) and take the next note (E). So we have the notes;
A-C#-E
Now we have our 1st chord. For the 2nd chord we will take the 2nd note (B) and follow the same skip/take pattern and continue doing this for every note, which will look like this:
1. A-C#-E
2. B-D-F#
3. C#-E-G#
4. D-F#-A
5. E-G#-B
6. F#-A-C#
7. G#-B-D
Every chord containing these notes are in the key of A. The name of the chords are as follows:
1. A
2. Bm
3. C#m
4. D
5. E
6. F#m
7. G#m/b5
Next post will explain how to determine each chord name.
