Back so soon?? Thats right, more music theory for ya to gnaw on! Last lesson was just assigning interval names to the notes of the major scale, now we can begin to explore dissonant and consonant intervals, with a major chord formula. A consonant interval is an interval that sounds peaceful, cheerful, and happy. Those are what Major chords are made of. Remember how the major sweep shape sounded happy? Its because of the consonant intervals! So now to make a C major triad (three notes, same as a C major chord, just a fancier name =D) you use the 1, 3, and 5 notes. In intervals, thats 4 notes from the root, then 3 notes from that note. You end up with "C E G", the notes of a C major chord.
Now if you want to make a major chord, all you have to do is:
1) Use the scale formula WWHWWWH to find the notes of your major scale
2) Take the root note, the third note, and the fifth note.
3) Now put each of those notes in a coherent order on the fretboard, and BAM you have a Major chord!
If you want to make a chord sound fuller, double up the notes, like adding the additional G note on the Low E string with your C major.
Sorry if its complicated, I am not too good of a teacher, and I am really trying to premeditate this as best as I can lol. So leave hate mail, rate mail, whatever you want in the comment box. You are all awesome.
