All right. Welcome to you. The third unit. Ah, and music theory for electronic musicians in this chunk, we're gonna be talking about a little more with keys. Eso a couple more tips and things. I want you to remember about being in key. Ah, working with the interval of 1/3 we're gonna introduce the third and our basic triad. And a triad is a fancy way to say Accord. It's a specific kind of chord, but, um, it is our most basic chord. So we're gonna talk about how to build cords, um, in this unit as well. So let's start off with one more thing about keys that I want you to keep in mind. So let me make clip. Here. Let me just load up my piano exam. Starting fresh for today. I always grab this one in the simpler grand piano. Okay, let's make this nice and big for us. Let's zoom in over here so we can see pretty well. Okay, so I'm just gonna get it started off. Ah, by writing in our major scale. Right. So let's start on C. Let's make a nice long see, it's make it two beats long Uh huh. OK, a...
nd let's maybe go up in octave. Just because I'm in that kind of mood, we want to hear it too low right now. Okay, Now, let's just draw the pattern of a major scale, right? So I'm just gonna copy the snow. Full step, whole step hasta will step, whole step. Whole step half step. There we go. Now, those are all the notes in the key of C major in this octave. Now, if you've ever played an instrument or worked with other instrumentalists at all, like a saxophone player, a clarinet player or something like that, you know that when we change a key, they have to do a lot of really quick thinking on their toes to remember all the notes of a given keep. So you might say, Okay, we're in C major, and they have to think Okay. Ah, yeah. Okay. I know all the notes of C Major, and they say, Okay, we're switching to the key of F, and that's, uh okay. Ah, and they have to figure it out in their head really fast. For us, it's a little bit easier. We don't have to memorize every note in every key because we know the pattern and the pattern is the same for all keys. All major keys anyway. Eso So if we want to figure out the key of F, for example, we can just do the pattern, The whole supposed to pass that pattern. Ah, starting on. And that would get us there. But there's another way to the other way is this pattern is uniform it it stays the same Ah, as we move it around So it's moveable as we say. So if I I'm gonna make this gross sound by just highlighting everything really quick, it's actually kind of an enjoyable sounded me now. So I'm in the key of C. Let's say I want to figure out the key of f This pattern isn't going to change. All I got to do is set what is now see to be f so I'm just gonna use the arrow keys way. There we go. Now I'm in the key of f. I'm just moving it up and down. If I want to be in the key of e boom now, I'm on in the key of e. Right. Um I want to be in the key of D sharp. This is what these air all the notes in the key of d sharp. So this is a movable pattern. Tow us. Now that's only true. If you're using all the white notes and all the black notes, is it a movable pattern? So, um, if you are playing, see major on a keyboard and you just shifted your hands up and ignored the black notes, you're not going to be playing the major, for example. Okay, here's C major, right. We had our hands on the piano on all the white notes. Now, if I move this two d major on and I just and I was playing the piano and I just like, shifted over Ah, it wouldn't necessarily work because my fingers wouldn't go to this f sharp and this c sharp if I was physically playing the piano. That's what I'm talking about. Um, because the black notes are kind of setback. There are a little bit different, Um, but when we're working on a piano roll editor like this, all the notes are the same, so we can just slide that way. All the notes are the same
