Learning how to read guitar tab is quite easy, all but one problem. Unlike standard music notation, there is no real standard to how TABS are written. The differences aren’t huge but you do need to get familiar with the various forms of guitar tab. Another major problem with guitar tabs is that there might be no indication of rhythm. This subject is a little bit misleading and really only affects guitar tabs that are created in ASCII, but even some ASCII tabs do have the rhythmic value included.
Guitar tab basics
We’ll start off with the absolute basics of guitar tab, how to read the notes. Guitar TAB consists of six lines, each line represents a guitar string. The lines are laid out as though you had the guitar lying down face up on your lap and were looking down at it, presuming you are a right handed player.
The vertical lines represent each bar and each bar is one measure. Because each line represents a guitar string, writing tabs is as simple as writing the fret number on each string. The horizontal axis equals time so you play each note on the fretboard from left to right.
The numbers on the fretboard below show the exact note order in which you would play the above tab.
Because the horizontal axis equals time, chords will have their notes shown in the same vertical line. The Guitar tab below shows how an A minor chord strummed four times in one measure.
So far so good, reading the notes from the guitar tab is easy enough, what we need to know now is the timing / rhythm information and how to read various guitar techniques such as slides, bends pull offs etc. This will depend on the various types of guitar tabs. Let’s take a look at these before moving onto the more advanced parts of reading TABS.
Various types of guitar tab
Three main types of guitar tab are the ASCII Tab, plain tab with rhythm information and Tab with notation.
Ascii Guitar TAB
First let’s take a look at ASCII Tab, this is quite a common type of guitar tab found on guitar forums. The thing that makes this kind of Tab unique is the whole thing uses simple text to reperesent ordinary Tab. Here is an example of the same chromatic run shown above but text generated.
As handy as this kind of Tab is, it has some drawbacks:
� If a monospaced font isn’t used then the whole thing can become an unreadable mess.
� It relies on a standard which is fine for fret numbers but can get messy when we need to show techniques like bends, vibrato etc.
� Rarely used with timing / rhythm information.
Basic Guitar Tab
Next we have basic guitar tab with timing information. This TAB lets us know the time signature and the note duration so that we know whether we should play quarter notes, eighth notes, triplets etc. This kind of Tab needs to be in image format for the web. It’s also used a lot in books and magazines.
Guitar TAB with notation
This is the ultimate kind of guitar tab, we get two staffs. One with full notation and the other with basic tab like the one above.
As we can see, guitar tabs with note timing value makes a lot more sense. Even though most text style of tabs you find on the internet has no indication of note duration, it is still possible to include it to an extent. Ascii tab exported from Guitar-Pro for instance does show note duration by placing text above the TAB. Here is an example of guitar Tab exported from Guitar-Pro using the same chromatic run as above played with eighth notes. The ‘E’ indicates an eighth note.
This is my approach to becoming familiar with finding the location of different inversions of the same chord on the entire neck of the guitar. The common open chords played at the nut and their shapes are the basis of this approach. This is very similar to what has recently been called the CAGED system, the name of which is an acronym of the open chord-shapes used: C-shape, A-shape, G-shape, E-shape and D-shape (C,A G,E,D).
.
By gaining a familiarity with these shapes and how they lead into and become one another, it becomes as easy to find any inversion (differently fingered or voiced form of the same chord) anywhere on the neck in any shape as it is to work with the common E-shaped barre-chord used so easily by so many. And then to progress into the more subtle voicings of basic chords as well. One way of imagining the concept is almost as if you were first asked to play a regular open at-the-nut C-chord, and then another C with a capo on the third fret (an A-shape), then a capo on the fifth fret (a G-shape), a capo on the eighth fret (an E-shape) and finally with a capo on the tenth fret (using a D-shape). Then it of course begins to repeat all over again at the 12th-fret an octave higher. Not quite that simple, but almost. I’m using the C-chord as an example (because if I’d started with another chord, like say E, than I’d have to call it the EDCAG system, and that doesn’t spell anything! 
Anyway, here goes……….

This is a diagram of a GUITAR NECK, not tab-lines. The symbol “0″ shows the location of your finger fretting that note in that fret position. It doesn’t mean open. Notes shown as “(0)” in parentheses are notes that fall within the chord’s major triad (its 1st, 3rd, 5th that make up a major chord), but are not generally used even though they could be used if that chord-form voicing, or inversion, if preferred.

Becoming familiar with these shapes and patterns allows you to move up or down the fret-board within them easily as well as the ability to use chord-fragments, or partial pieces of these shapes/chords which can be played individually or strung into a linear pattern. Used linearly, you can arpeggiate flowingly or create note-lines, choosing say a treblier flow, like this for example…….
E||-----|-----|--0--|-----|-----|-----|-----|--0--|-----|-----|-----|--0--| B||--0--|-----|-----|-----|--0--|-----|-----|--0--|-----|-----|-----|-----| G||-----|-----|-----|-----|--0--|-----|-----|-----|--0--|-----|-----|--0--| D||-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----| A||-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----| E||-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----| ^ ^ ^ ^ ^ ^ nut 3rd 5th 7th 9th 12th . . .....or a bassier line..... .

….or of course any combination of both that you may want to use. And of course any of those shapes can be combined with part of the shapes above or below it. For example 7 8 10 0 X X is a C-chord that combines parts of three separate shapes (the open C-shape, the open G-shape and the open E-shape) into a C-chord. The more familiar you become with the pattern, the more ways you can find to use it.
.
Now, expanding just a little bit on that shown above. Once you are familiar with all the shapes above and comfortable locating and using them on the fretboard, you can draw on the knowledge you have of THOSE SHAPES THEMSELVES when used to form the common open chord OF THAT SHAPE. For example, it’s easy to remember how to change an open A-chord X02220 into an A7 X02223. You just add that 7th note on the first string. Or it can be changed to an A7 by holding X02020, changing that 3rd-string to open. Same with a simple open E-chord 022100. Just add the note on the 2nd-string…022130, or change the 4th-string from 022100 into the E7 chord 020100. The common G-chord can be changed from 320003 to a 7th by using 320001 or 323003. A D-chord by changing from the common (2)00232 to the 7th-chord X00212. All of this knowledge can be applied in the same way TO THE SAME SHAPES up or down the neck. Here is the entire C-pattern (shown above as major chords) with some of the 7th-notes added (shown as a “(7)”)
E||----|----|--0--|-(7)-|-----|-(7)-|----|--0--|-----|-----|-----|--0--| B||-0--|----|-----|-----|--0--|-----|----|--0--|-----|-----|-(7)-|-----|-0- G||----|----|-(7)-|-----|--0--|-----|----|-----|--0--|-----|-----|--0--| D||----|-0--|-----|-----|--0--|-----|----|-(7)-|-----|--0--|-----|-----| A||----|----|--0--|-----|-----|-----|-0--|-----|-----|--0--|-----|-----| E||----|----|-(0)-|-----|-----|-----|----|--0--|-----|-----|-----|--0--| ^ ^ ^ ^ ^ ^ nut 3rd 5th 7th 9th 12th . C-shape area...A-shape area...G-shape area.....E-shape area......D-shape . (now C7-shape....A7-shape.....G7-shape.........E7-shape......D7-shape
Now I haven’t shown every 7th note necessarily, just the more common ways that the chord-shapes are changed in the open positions. This same logic applies to all other voicing-changes, like from a major into a minor, or into a suspended chord, or an augmented chord, or a 9th….whatever. The more you are familiar with how to change the voicings on the simple open chords, the more this basic information can me moved up or down and then applied to THEIR SHAPES anywhere on the neck.
.
.
Being familiar with this information has a secondary use as well. Knowing the locations of certain simple parts of a chord, like its 1st or 3rd or 5th (or its 7th, etc) will give you locator points-of-reference to make more complex changes, or to swing scales from when doing lead work. That’s why the knowledge of chord-building is of so much importance. You don’t have to really think in terms of chords themselves, but in CHORD-SHAPES. Take all of that information on the neck-diagrams shown above. That was all in reference to working with a C-chord. Grasping the pattern and movements and relationships of the shapes themselves makes it easy to take that same pattern, and by simply in effect moving the pattern two frets —> you now have all of that applied to a D-chord. Or three frets <—- opens it up for A. And so on. Think of the pattern as the Constant that will never change in how it works or in its application. And think of the fret-board itself as the Variable that changes beneath that Constant pattern, almost as if the fret-board was a tread-mill that will rotate below the fixed pattern of the shapes above it, changing chords and keys as it does.
