To get back on track, as a sort of "interlude" and as promised - kinda triggered by
@bucephalus - here's some true horrorshow cowboy chord stuff, which I will try to make a little more acceptable (and if only from a player's POV) using the very triads discussed so far.
I'll stick to the key of good old C major and use one of the most common chord progressions in existance, namely the 1645 progression, in roman numbers: I-VI-IV-V.
Hence, the chords used will be C-Am-F-G.
I'd almost take a bet that pretty much everyone has already strummed these (or something very similar) on their acoustics in the beginning of their career, possibly struggling a bit with the F, kinda faking their way through it, likely using a "not so complete" barre version, as in leaving out the A5 and E6 strings or whatsoever.
Anyhow, when you hear it, it'll be instantly familar.
And instantly cheesy! Don't say you haven't been warned!
So, I tried my best to use lame drums, bass, piano and guitar patterns for a start. Uninspiring all throughout, to put it mildly.
Next I added two guitars just using the very kind of major and minor triads I was trying to explore so far to improve the situation. I'm not saying it's acceptable music all of a sudden (we all know about the non-polish-able turds), but at least these kinda parts are more fun to play and IMO it's at least a little more acceptable for the audience.
8 bars of pure horror, 8 more bars of slightly less horror:
No idea whether this demonstrates anything properly for you folks, but personally, I defenitely think it's a noticeable improvement. Anyhow, it basically was just to show a sort of real life example (unfortunately, I sometimes have to deal with less than enjoyable music, things like this help me to get along with those situations).
Here's what I did. The left (almost faux slide) guitar is playing the chords very strictly as written:
So, a really easy part.
For the right, more "rhythmi-sized" guitar I was using a little bit of additional movement by approaching (or "embellishing") the target chords by other triads from C major. Without going into any details about the hows and whys, this is something you can do with pretty much any chords out of the key. Just release them to the target chord in time and you'll be fine.
Otherwise it's exactly the same triads as already covered:
And that should be it for now.
I hope you've enjoyed that marvellous (or should I better say "mindnumbing revolutionary"?), emotionally pleasing piece of art!
