 Right, so what is this chord? It's a very mysterious one, right? So I use this chord a lot sometimes without any context, you know Someone just at at some point in a song you just need something really weird and Interesting and you know just really weird, you know, so you can just add this chord whenever you'd like So this is nothing but an augmented chord with a dominant seventh So we call it an augmented seventh Or you can call it a dominant seventh or a seven sharp five All of these names could exist. Okay, so how do we build it again? You could start with your D major third up F sharp Then you take your normal fifth, which is a what would have become the D major chord, but you raise that by a step Okay, and then you add the dominant seventh Very very mysterious and very dreamy sound So one way of using the dominant seventh sharp five or augmented seventh chord is just like that The other way is actually to give it some context and some purpose, you know It could be a dominant resolution chord in other words you play the chord and it could resolve to The tonic major, okay Or even the minor In some way, but it really depends on your melody if your melody has that Right, I also like resolving it to a major sixth Or just a normal major Okay, so you could use it just like that to add some Serious interest in your music, especially if you're doing like film score compositions and stuff like that These chords work really well. I don't think you're expected to create a scene change in a film score context With either a major chord or a minor chord. Those are not the money cards as you call it These chords are really going to work, you know for a scene scene change Even the one I talked about first the minor major seventh a lot of these chords, which I consider my favorites You can just use like that. You may argue which scale is this part of well You don't need to care. Just use it, you know Just form it and it's a very enjoyable just to play that one chord, you know, so again D7 sharp 5 also known as D augmented 7th. Let's move on
