Answering the most common music theory question I get, once and for all!!! Also my best musical experience, favorite dinosaur, the difference between major 6 and major 9 chords, and much much more! Here’s a link to the Fender Ultra strat I’m playing:

A little about me:
Sean Daniel is a man. A man of simple needs and desires. And the one desire, no, the one NEED, that stands above all is to spread the challenges, joy and intellectual stimulus of music to people of Earth and beyond.
Born on the mean streets of upper middle class suburban Chicago, Sean learned the ways of the world through the dizzying heights of success to the lonesome depths of failure and emerged with the promise of a better tomorrow reflecting in his eyes and fiery passion in his belly.
He plays and teaches guitar on his YouTube channel where he regularly releases original music and projects to the adulation of legions of fans, who often compare him to Chris Pratt and one time Ryan Reynolds. He’s currently in the market for a nice leather jacket.

Juan Gutierrez says:

The part that confuses me is that if you stack 3rds of any scale degree to create a chord, why do 2-3-6 have minor thirds? I've just accepted they do. How does a third magically become a minor third for 2-3-6?!

If I start on A (5th fret E string), the 3rd interval is major 3rd C# (4th fret A string). Now if I go to the second degree, B (7th fret E string), in the scale and build the chord stacking a third, the third should be E flat (6th fret A string) but it's not, it's a minor third because 2nd degree chord is a minor chord.

So either you don't actually stack a 3rd for the 2-3-6 scale degrees, you stack a minor thirds. Or by stacking a third, they don't mean literally playing the major scale with each degree as a new root. Because that's how I understand it, and it makes no sense. Stacking a third on B, gets me a major third, by definition a third is major. So I have no idea why it would be a minor 3rd on the B chord (2nd diatonic chord in key of A)

How to make something relatively simple so complicated. And then, a big sales pitch. Ugh.

Automaticman88 says:

1 + 4 = 5 (Major) 2 x 3 = 6 (Minor)

It must be frustrating for YT teachers to have to go over the basics all the time. At least in college we get a course with definite content and progression. It's only difficult if you have some who aren't keeping up.

I will share all the nut butter I have with you. Just because you have taught me so much, and you entertain me daily.

Major 7 is my favorite chord 1357. Spelling vs degree was an epiphany during my music theory [self] training.

Joel Zdepski says:

I think you said the right things for either the wrong reasons or missing the reason. You jump to saying you make the V and VI chords by taking the 1,3,5 from their major scales. That is not really the reason, it is an observation. You make "standard" triad chords by picking the degree of the scale you working with and taking that note as the root, skip the next one, add the next one, skip the next one and add the next one from the scale. It is the structure of the major scale that imposes that for the VI and V the intervals correspond to major chords and for ii, iii and vi they are minor and for vii diminished. Your explanation at that point of saying that VI and V were major sounded magic. I think that is why this topic is confusing, it often feels like some arbitrary switching to other scales is going on, which of course is not happening. Of course, when later in ones guitar journey you can do chord following scale soloing it becomes a wonderful thing and that is when you can take the view of the V and VI are associated with their own major scales.

Becomes easier to understand music theory if one first learns piano

Lancelot Link says:

In one case we are talking about the intervals that make up a chord (1,3,5). So the first interval, the major third interval and the perfect 5th to make a major chord. But when we talk about the CHORDS of a major scale it's helpful to use roman numerals to provide some clarity. So if we say play I, IV, V of C we want to play the chords C, F and G. Each interval of a scale has a chord associated with it. So in the first instance we are talking about the intervals of the scale. In the second instance (using roman numerals) we are talking about the chords of the major scale.

Thanks for this Sean! It was very helpful. Your style and teaching methods are so useful..We are so lucky!

I feel everyone thinks that they're just playing stuff that sound like you know what you're doing. Like if John Mayer explained Neon saying "It's not really that hard but it makes you sound like you know what you're doing"
