the chain

[iBot]

hi guys

I want to play the chain on this bass I got.

I know nothing about playing music, but it should be easy to play as it only has four strings.

i;ve found the tabs here.

I just want to play the "F1 bit".

So, How do i do it?

I twang one string and it sounds like a bit of the song, so i guess a bit of it is played open string?
