let's take a look at secondary dominance basically all we're doing is we're taking a chord from another key and putting it into a chord progression but how does that all work and how you know which course to use that's of course the question so first let's take a look at this diagram this is showing all the chords in the key of C and a Roman numeral associated with each of them this is from functional harmony theory I made a video on that last week and have a link to it down in the description if you want to check that out before watching the rest of this video so using this diagram we can see that the five chord is G now in functional harmony the five chord wants to go to a 1 and we also call the 5 chord the dominant by the way so that's where that part of the name comes in but anyways here the 5 chord is G and so in this particular example G is one to go to C five to one now bear with me for a moment and let's talk about the key of G and the key of G the five chord is d right to D wants to go to G five one progression here okay so now forget about G for a second we're gonna go back to C let's go ahead and let's make chord progression in the key of C this is a very common progression we'll go 1 4 5 1 or C F G C right so check us out [Music] now let's take a look at that G chord in the key of G we know that the five chord is d so we put D before G a D major chord which isn't a chord in the key of C then it's like we're using the five chord of our five chord in the key of C it's a five of five as it's called so if you see here you can see that D is the five chord of G Baba you get the idea so you see where we're kind of pulling this gets a little bit complex because things are going in a bunch of different directions but just listen to how it sounds because it has that 5-1 resolution from another key within the key of C check it out we're gonna go one four five of five which is our secondary dominant chord to five and then one here's what it sounds like [Music] [Music] pretty cool right and that's really all there is to it we just we decided that we wanted to do a five of five so we took our five chord in the key of C and we tried to figure out what the five chord was in the key of G because G is the five in the key of C right so a five of five that's basically how it works now we can take this a step further and we should honestly because you don't have to have just a five of five you can have a five of two a five of six a five of whatever so let's let's look at one of those let's look at a five of six so in this case we're going to the six in the key of C which is a minor and we want to figure out what the five chord is in the key of a minor so we'll look at this a diagram looks a little bit different when you're looking at this functional harmony stuff but here is a minor right written out in functional harmony so we're going to look at the five chord here which is an E and we look back at our C major diagram and we see EE obviously is not a chord in the key of C but we can use it as a secondary dominant so it's a five of six so now if we would have a progression that went one six five one we could add in our secondary dominant and change the progression to one five of six six five one listen how that sounds [Music] now this can also be used in minor keys like for example in a minor you could have a 5 of flat 3 whatever you want to do you can have a 5 of anything and you can have multiple 505 in a progression there's enough to just be one but this is essentially all there is to secondary dominance and it's really all you need to know as an added note if you want to make any of these 5 chords a dominant 7 you can totally do that and it actually in some cases will sound better so you know for example with our five of six that ecord could be an e dominant 7 chord it sounds a whole lot better that is if you if you're not familiar with what dominant 7th chords are that's fine don't worry about it but that is if you if you are familiar that's something you can add in and it sounded really good all that being said please let me know if you have any questions this was kind of a quicker explanation of a theory topic so I'm kind of experimenting I guess with a different style but it took me a long time to wrap my head around secondary dominance had to be explained to me like five times from a bunch of different people before I before I'd ever clipped for me so if you're having trouble comprehending it or something let me know I would be more than happy to help you with it and that being said um a friend of mine here on YouTube at Orchestra studios did it a video on this as well and so it's just another perspective on it if you want to check it out so I have a link in the description to that video too I think it's really helpful to get different viewpoints on some of this stuff alright guys thanks for watching and see you next week [Music] you
