What do "parentheses" mean in tab?

[bunnyo]

Hi,

I'm trying to learn to read a little tab for the solos in And I Love Her. I have some figured out, other things baffle me.

For instance, what do the parentheses mean? I recognize them as chords, but it's confusing how many to play in a bar, etc.

Thanks,
Bunny

Believe it means to hold the note/chord through that beat without playing it again (let it keep ringing).

Thank you, rainbow , that makes a lot of sense
