So tabs can be kind of hard to figure out at first, but I'm here to help!
So this is a rather crappy picture quality but usually tabs have 4 lines, the top one is the A string then the E, then C, and finally G. There are also numbers.
The numbers are a reference to the fret. A Frey is the space between the bars.
Let's say the tab says 3 on the A string, this is what it would look like.
Okay a harder one. There's a 2 on G and a 1 on A. This is what it looks like.
