hi all.
i have a very simple question. what does a black circle mean on the right of C chord diagram. you can see it on any song found here that has the C chord when you point the cursor over the letter C for example? its a small black circle over the A string. what do the white circles mean?

Thanks a lot in advance from serbia.
i am very greatfull for your answer or explanation

Never actually noticed that. It appears that the black circle is your route note and the white ones are other strings that should be played and allowed to ring out. Ones with 'X's next to them should not be played or muted
ok thanx both for very quick reply. PSimonR can u give me a short explanation of it's use.
