The Major and Minor Third

okay, It's time to talk about with third now. Third is not just another interval like the octave or the fifth. This one has a peculiar thing that we have to deal with when we deal with the third, and it's very important. So to understand it, let me go back a little bit. I talked a minute ago, the major and minor and the biggest interval that changes between Major and minor is the third. Ah, in terms of I shouldn't say the biggest interval. I should say the most important to us in terms of making cords, which is what we're about to be doing is the third. The third is very important for cords, and the third is what makes the difference between a major and a minor cord. So let's Cohn, let's find 1/3. Okay, so this is relatively easy, right? I'm on C. So I'm gonna go up some on 123 There's my third c t e is 1/3 in the key of C major. If I count up to notes in the key, I get to 1/3 That's 1/3 now. This is a major third let me show you what a minor third looks like in to demonstrate that I'...

m just gonna put the whole C major scale up here one more time. Here's my major scale it zoom in a little bit. Okay, so this is a major scale. Let's count up 1/ from D in the key of C. Not in the key of D. Some is going to stick to the key of C buying an account from D up to 1/3. 123 So D toe f eyes 1/3 on C T e is 1/3 cap. Hold on to that for a second. Let's focus in on just those two. Interval. Throw that away. Let's move that there. And let's move these two notes out here just so I can take a good look at him. Okay, this one c t e is the major. Third, this one did. A F is a minor third. How do we know the easy way to know is to count up on Lee half steps? Okay, So 12345 5/2 steps. Including the first and last note here. 1234 That's the difference. the difference between a major third and a minor third is one half step. So this is a major third. If I wanted this to be a minor third, I would take the third and I would lower it 1/2 step. This is now a minor third because this is only for half steps away. Put that back up to a major third. This is a minor third. If I wanted that to be a major third, I would raise it 1/2 step, which would take it out of the key of C major. Um, and that would make it a major third because I would have 5/ steps in between. But a major third built on D does not occur in the key of C major right, because that would require an F sharp, which is not in the key of C major. So as you build thirds throughout the scale, way have different alterations of major and minor. Third and not alterations, meaning like blue go major than mine. Answer the major turn. They don't go back and forth that clearly. It's just there are some major on some minor thirds as we go up there. Uh,

this is great and very helpfull class, i make and wirte music for more than 2 decades and never gave much about theory, i trusted my feelings to what sound good and what not. Bu t recently i became interested but it all seemed very difficult to me and i didnt got the points behind music theory and how everyhing works together. This class was a game changer for me.. music theory is so simple if you have somebody to explain it in words so that you finally can understand it, and thats Anthony, he is a brilliant guy and he explains it in a simple way that you can easily understand whats going on. This is perfectly the case with this course, the sections are short and to the point, not much talking around and leaving the path, you can make fast progress end learn how music theory works, this is a 5 Star ***** course and hopefully there is more to come

Fabulous course. As a person with dyslexia, trying to remember the notes and chords as letters only is impossible. I love the visual way the chords are demonstrated and explained. I was originally put off by the "electronic" aspect, thinking it was only for learning how to use piano edit roller. However, as a beginner in playing the piano, this course is applicable to all who want to learn and understand music theory in an interesting visual way. Looking forward to next lesson. Will definately be purchasing the course after. Fantastic tutor and course.

Very good class!! Makes it much easier to understand and apply the rules of theory. Anthony is also very wise to suggest to trust your ears, even if what you've written doesn't fit into those same rules. I am so very grateful for you putting this together, Anthony, and for making it available for the general public, Creative Live. I am also very glad I was given the opportunity to learn english in my home country (Brazil), in which many barely know how to read and write in our own native language (portuguese) due to our public education being so bad (which, by its turn, has to do with the myriad of vile creatures that inhabit our representative chambers). Tks XoXo!
