ska licks anybody?

Hey I am an intermediate player would like some tips on playing ska licks.

Never much played Ska so best I can say is emphasize on the upstroke. For instance, if you were playing over a 4/4. Standard riffing might have to empahsize on the downstroke at the 1 and the 3 ( 1 - 2 - 3 - 4 ) but with Ska, you are upstroking on the 2 and 4 ( 1 - 2 - 3 - 4 ).

Then again, I never really played it so I could be totally wrong.

So, here's a little vid that should give help. I seem to remember that Ska jumps from major chords to minor chords (and maybe some sevenths).

It looks like Nick Marchant is working on ska as we speak:

Take a look, and maybe ask him if he can add some licks...

Any punk licks will help. I have my power chords down. I just need some patterns using all the strings. Anything in punk style will help tremendously. Thnx again. Azpunk
