how do you read guitar tabs?

Answer 1

From left to right; the numbers indicate the fret. If tabs are too hard to read, I suggest learning how to read real music, it'll be worth it.

Answer 2

Each line indicates a string. The top line is the high E string and the bottom line is the low E string. The numbers on each line indicate the fret to play on that string.

Answer 3
