Notes that are played at the same time are represented at the same horizontal position; another way to say this is that the note indications are "stacked" vertically with respect to one another when the notes are to be played at the same time.
In your example tab, none of the notes are played simultaneously.
Here's a strummed open E chord (all notes played simultaneously):
|-0------|
|-0------|
|-1------|
|-2------|
|-2------|
|-0------|
Here's a picked pattern with simultaneous notes on beats 1 and the 3:
( 1&2&3&4& ) = (beats)
|----0--0--|
|--0--0--0-|
|-1-1--1---|
|----------|
|-----2----|
|-0--------|
The first thing you do in this TAB isHer's a "pinch" with the thumb on the 6th (low-E) string, and the index finger on the 3rd (g) string. A similar pinch occurs on the 3rd beat -- but now using the thumb (on the 5th string) and the middle (on the 2nd string).breakdown:
- The first thing you do in this TAB is a "pinch" with the thumb on the 6th (low-E) string, and the index finger on the 3rd (g) string. These note indications occur in the same column, indicating that they should be played simultaneously.
- The next, on the "and of 1", is to pluck the 2nd string with your middle finger by itself (no other note indications appear in this column).
- The next, (on 2) is to pluck the 3rd string (with index) by itself
- On the and of 2: it's just the open 1st string (with ring finger)
- A pinch also occurs on the 3rd beat -- but now using the thumb (on the 5th string) and the middle (on the 2nd string).
- etc.
