Chicken pickin' is the next thing I'm throwing myself into. I absolutely love the sound of it and there's so much ground to cover there, creatively and in learning existing music I never had the balls to attempt before 'cuz I can't chicken pick!
For me, apart from a bit of chicken picking, the main things I learned from doing a bit of country stuff are:
- Hybrid picking. Sure, can do this within other styles, but chicken picking lends to it.
- Bending in general, including faux slide playing, using both bends and the whammy bar (fwiw, Lukather is incredibly good at fake-sliding with the whammy). When you dive into that just a tad deeper, you'll find yourself bending each string with each finger in each position all of a sudden. Sometimes quite a painful thing (for instance: your index finger has zero supporting fingers behind it, turning bends into an exercise in "oooouch-ohhh-grrrrr!").
Fwiw, I played 11-49s for over a decade on Fender scaled guitars /w floating vibratos. Turns any kind of country bending really into some sort of, shall we say, "interesting" experience. Not only does it require *way* more finger power compared to doing things on, say, a fixed bridge Tele with 09s (which seems to be a pretty common gauge among the most bending folks), if you want to do double bends (or rather bend one note while holding further notes on the other strings), you will have to compensate to get it done properly because of the free floating vibrato (which is why I often "mask" these things by using the whammy bar as well).
I'm now back at 10s with on my vibrato guitars, helps quite a bit.
And now:
- *The* biggest thing: deeper harmony understanding, or rather: deeper skills when moving around in harmonies. Yes, for real, even if country music often appears as seemingly simple when it comes to harmonic means.
From my experience, many people never thought about that aspect, so let me try my best to explain the hows-and-whys (no idea whether some of you fine folks are interested in my findings, but hey, I'll try anyway...).
At one point in time, I started noticing how many country player were rather fluent in other styles as well (mainly when it comes to some sort of jazzier harmonics), especially when improvising. I've once been at a session where there's also been one of the (very few, they're a super rare breed over here) most proficient pedal steel players in mainland Europe (Nils Tuxen from Denmark). Now, all of a sudden they started jamming some funky fusion kinda stuff and my jaw simply dropped about what that guy was pulling off. But that was just the tip of the iceberg.
You can take pretty much any of the famous country pickers, be it Vince Gill, Albert Lee, Brent Mason, Johnny Hiland or also someone like the more traditional Chet Atkins - they will *all* do quite fine when it's getting jazzier (heck, you could easily slap Mason into a fulltime jazz band, he's just sooo good).
And as an important secondary observation: the same is *not* true vice versa. Stick most accomplished jazzers into a harmonically simpler (but still functional) context and most of them won't do well, to put it very, very carefully.
Now, how is that? How is it that folks performing seemingly simple music are doing so incredibly well in what is usually considered harmonically complexed music? Well, fortunately there's Mr. Franck to bring you the answer (pfft - no, seriously, you don't find these observations often, but it's nothing that special, once you think about it...).
Let's start with a single, simple tonic chord in jazz. And for easiness sake, that's gonna be our good old C major chord.
Now, in jazz, there usually doesn't exist a C major triad, so the chord will be more or less massively enhanced. The first thing to happen usually being that a 7th (or 6th, typically when forced by melody or whenever an oldfashioned sound is asked for) is added. So instead of a vanilla C-E-G chord it's gonna be C-E-G-B(A) already. But it doesn't stop there and we'll often find "option" notes added, in this example it'd usually be a 9th and/or a 13th. Our chord would then become C-E-G-B-D-A. And in case you're just slightly more adventurous, you might treat that tonic chord as a lydian chord and add the #11, too. C-E-G-B-D-F#-A would be the result.
Note: If anyone wanted, I could happily explain chord construction (both theoretically and how to deal with them on guitar), but for now that's not exactly relevant, you just need to believe me, hrrrhrrrhrrr...).
Now, when you compare that to your typical "country tonic chord", you'll likely find that there's no such harmonic experiments happening. Pretty often, it's gonna be a plain triad being used, not even a 7th chord - the latter making a lot of a difference, btw., once 7th are used, our ear is sort of pre-prepared to deal with further option notes as well (quite a simplified explanation, but see above, you'll just have to believe me for now).
Anyhow, regardless of whatever functional background, in an extremely simplified X vs. Y setting, we're ending up with:
Country: C = C-E-G
vs.
Jazz: Cmaj7/9/#11/13 = C-E-G-B-D-F#-A
Jazz being the clear winner here, because more is more, isn't it?
Just that it isn't. Boo!
And now (*drumroll*) it's getting interesting for us mere noodling guitar slingers.
Pretty much the same chord/option note "rules" apply to the target notes of our melodies and noodlings. In other words, in a simple country-ish triad based chord context, your only landing zones within a (typical) 7 note scale are 3.
In a jazzier context however, this number goes up to 6 options already - or, should you feel comfortable with the lydian mode (over major chords at least), even to 7. Within a 7 note scale.
So, for this stupid (or not so stupid, really...) example, let's assume you were noodling mindlessly just using scale notes in either style and are now supposed to hit a proper target note on the next beat one without any preparation. That's a 3/7 chance of hitting a proper note vs. a 6/7 or even 7/7 chance. I'd say that's *quite* a difference, right?
In other words: Hitting the right notes is a lot easier in jazz than in country.
And yes, before anyone gets on me, this is extremely simplified but IMO there's a WHOLE lot of truth behind it (which is proven empirically, see my comments about most decent country players being able to play some jazzier stuff as well, whereas it's usually ending up in epic fails the other way around).
And then, it doesn't stop there.
Typically, country is highly functional music (fwiw, the backing I was just noodling around with isn't the best example as it's located much more in the bluesy realm) and when fooling around with it your playing needs to do that justice.
As another example: A very typical chord progression in the key of C might be something using just tonic and dominant chords, namely C and G.
C is C-E-G
G is G-B-D
So, a) there's just one common note (the G), and b) for either chord, there's still no higher but a 3/7 hit'n'miss chance.
In jazz, the same progression might be Cmaj7/9/13 (leaving out the 11th, resulting in the F to become an avoid (aka "bum") note) and G7/9/13 (again leaving out the 11th, which would be the C).
In notes:
Cmaj7/9/13 is C-E-G-B-D-A
G7/9/13: G-B-D-F-A-E
Many more common notes (5) and just one scalar note to avoid per each chord.
As with the single chord example, we've got vastly less landing space for our target notes and we will now also have to be dealing with properly adressing the issue of having very little common notes. As a blunt (but pretty much suitable) example: Let's assume you've got some scalar licks ending on various degrees (notes) of the scale. In the jazzier realm, not only could you use much more of these licks, ending on pretty much all scale degrees, no, at least in our example, you could even use 5 of them for either chord vs. just one (1!) for our country-ish progression.
And as if all that wasn't enough already, country players typically are extremely familiar with approaching target notes chromatically. That's a pretty welcomed thing in jazz, too - and as you have way less target notes to connect chromatically in country, you need to be much more eloquent with those chromaticisms compared to jazz where pretty much every other note of the chromatic scale will be a suitable chord based target note.
Phew, ok, that should be it for now.
And again, just to make sure: this is super simplified. There's jazz with much more complexed harmonic structures, there's also country with more than major keys and their respective triads, etc., so take all of the above with a healthy dose of salt, but as long as the barebones are concerned, I found all this to be pretty damn well applicable, especially as I've seen quite some examples - basically and most often as in jazz players pretty much failing as soon as less complexed harmonies were involved, but also as in folks familiar with country and related stuff being pretty fluent in other styles. The really great players of either style will not fall into any of these categories anyway.
Still, learning country-ish, simple triad harmony comes with huge benefits, especially in terms of improvising.
