Okay, so I have this neighbor who's in his own local band, and 
yesterday a bunch of people came over to my house after we went 
to see my mom sing at the coffee house. He told me that this was 
a riff that his band played, and the nifty thing about it is that 
it was (allegedly) in 5/4 time. Anyone who's ever played anything 
at all in 5/4 knows that it's the most bizarre time signature 
out there.

Now, of course, since someone had just invaded my individual 
practice session, and on top of that impressed me with this nice 
riff, I spent a little bit of time playing around with it. So, 
here it is, this neat riff in 5/4 time which I have tweaked to my 
own style, keeping intact the art of repeating and how it makes 
for a good practice, and for a funky song part.

By the way, it's standard tuning. Play it however you want ... 
no specific rhythm or anything.

G|——————————————————————————————————————————————|
D|———————————0—0—————————————————0—0————————————|
A|——————0—0———————0—0———————0—0———————0—0———————|
E|—3—3—————————————————3—3—————————————————3—3——|

That's all he taught me, but I added some stuff. Since he said 
the bassist did something else, but he didn't show me what that 
"something else" was. So, here it is:

G|———————————0—0————————————|
D|——————0—0———————0—0———————|
A|—3—3—————————————————3—3——| (Yes, I know all I did for this one was move up a string)
E|——————————————————————————| 

G|———————————————————————————————————————————————————————|
D|—————————————————————3—3——5—5——3—3—————————————————————|
A|———————————3—3——5—5—————————————————5—5——3—3———————————|
E|—3—3——5—5—————————————————————————————————————5—5——3—3—|

G|———————————————————————————————|
D|———————————————————————————————|
A|————————2——2——————————2——2—————|
E|—2——2—4——————4—2——2—4——————4—2—|

Well, that's about it. Keep in mind, they can all be played on 
any fret, or any string. Here's one of my favorite sequences 
involving the last part:

G|————————————————————————————————————2——2———|
D|——————————————————————2——2———2——2—4——————4—|
A|————————2——2———2——2—4——————4———————————————|
E|—2——2—4——————4—————————————————————————————|

That's about it. Play it on any fret, any string, in any key, doesn't 
matter. My style tends to be a bit different, but oh well, it doesn't 
sound too bad. Good luck :)
