By the way, what the fuck is a neopolitan chord?
Dude, we just explained it like four times...
And I had no idea what any of it meant. I realise a triad is three of something, but what does it mean? Is the major triad just the 1st, the 3rd and the 5th, or waht?
Well, I would worry about learning triads and scales and stuff like that before worrying about Neapolitan chords... But yes, a major triad is the 1st, 3rd, and 5th scale degrees of a major scale. C, E, and G, for example, is a major triad. It's a major third between the bottom two notes and a minor third between the top two notes (in root position, before anybody pounces on me about inversions...) Like I was saying before, if you're in the key of C Major, a Db Major triad would be the neapolitan, which would be Db, F, and Ab. It functions as a predominant, meaning that you play the neapolitan, then go to the five chord (G in C Major), then most of the time to the one chord (C in C Major) for the resolution.
As Timehat said before, you can use it going ii - bII - I, which almost functions as a dominant feel, but it's not really a dominant resolution seeing as it's not a dominant chord. The tritone substitution is moreso a means of voicing in the jazz language. What this resolution creates is a descending half-step line to the tonic for the resolution instead of the dominant-tonic motion in an authentic cadance. You also wouldn't really use this resolution in the classical realm without some fancy voicings because of parallel fifths.
This music theory stuff seems to me like just a big circle-jerk.
It is. Why do you think that I and so many others find popular music so damn liberating?
A Neapolitan chord is where you take the root note of the scale, move up two semitones, move one back, and build a major triad, which is the first, the major third and the fifth. See how easy that was to explain, guys?
Or couldn't you just move up one semitone? Or to make it even easier to understand, one fret???
Popular music gets boring because it's always the same chord progressions over and over. Sure, classical music can get boring because there's a lot of repetition going on there too, but they have more material to work with. Sometimes I love the simplicity of popular music, but some of the stuff is ridiculously boring.
