7th Chords - Overview
okay up next. We need to talk about seventh chords now. Seventh chords are not chords with seven notes. Um, that would be pretty extreme, considering that so far we've only had notes or records with three notes, Right? Ah, seventh chords are chords with four notes. So how does that make any sense? Well, let's just I didn't So let's make a try it. Actually, before we make the Triad, let's make the whole scale again. I know you're getting sick of this, but it's important. Ah, and it'll it'll really help us to see why we call these seventh chords in that fourth courts. So I'm gonna make a C major scale, full step, whole step, whole step half step. There we go now to make a triad, we use the first, and then we skip a note. Third and the fifth, right? What if we kept going? What if we went one more step? So we skip a note and we add the seven. That is what 1/7 chord is. So we have four notes, but the notes we have our 1st 3rd 5th and seventh tone of the scale, right? That's what we call him...
seventh chords. Fairly easy, right? So what do they sound like? Well, let's get rid of these other things. So here is 1/7 chord. That's what it sounds like. Drag it out a little bit. Ah, it's Ah fairly pretty sound. Now the dangerous thing here is that there are actually three different kinds of seventh chords. There are, ah, a major triad with what we call a major seventh on it. That's what we're looking at here. But then we can also have a minor triad with a minor seventh. It's a little bit more of a jazz sound, and we can also have a major triad with a minor seventh. That's what we call a dominant sound that's called a day dominant chord. We'll talk more about that in just a minute, but those are three different flavors of seventh chords that we encounter in the diatonic chord progression. So if we made the diatonic chord progression going all the way up, but we added seventh chords this time, we would have some major seventh chords. The major seven chord is this 1st 1 a major triad with a major seventh with 123450 that's gonna be a major seventh. Sometimes we'll end up with a minor chord with a minor seventh. That sounds like this. That is a minor seventh with a minor triad underneath it. And sometimes we'll end up with a major triad with a minor seventh on a diatonic scale. That only happens once. There's only one chord that gets it. So we'll talk about that in just a minute. You might say to yourself, Hey, you skipped one. What if we had a minor chord with a major seventh? That doesn't really occur anywhere in the ah scale, so we don't use that one very often. That was pretty rare. Ah, and it's kind of a different kind of chord. We'll talk more about that, I think not in this class, but in the next class. So those are three different kinds of seventh chords. Ah, next let's go into looking at ah, how to use them
