Alot of guitarists hear the word "theory" and they turn and run as fast as they can... But theory is not as scary as it seems. Let me put it into perspective for you... There are 12 notes... That's all... Now, let me clarify, each of those 12 notes can be played at different "octaves", but all in all there are still only 12 named notes. OK guys, let's roll up our sleeves and get started The 12 notes chromatically C C# D D# E F F# G G# A A# B (then you start over at the next octave) or C Db D Eb E F Gb G Ab A Bb B For those who might not know..C# means C"sharp" and Db means D"flat" Now the C# and the Db are the same note, it just depends on what key you are playing in as to which it is called... That's another lesson. On a fretboard that looks like this
e--------------------------------
b-1-2-3-4-5-6-7-8-9-10-11-12-13--
g--------------------------------
d--------------------------------
a--------------------------------
E--------------------------------
The "distance" or interval between each note is a half step or 1 fret Pretty easy so far right? Now from those 12 notes, we are only going to use 7 of them to get the major scale... You Have To Learn This!... I'll show you the key of C since there are no sharps or flats and it's easy to remember.
C C# D D# E F F# G G# A A# B C

C    D    E F    G    A    B C
You learn to build the major scale by learning the intervals between each note..example..between the C and D there are 2 half steps, or 1 whole step, 1 whole step between the D and the E, 1 half step between the E and the F, and so on...
1   2   3   4   5   6   7   8(1)
C   D   E   F   G   A   B   C
  w   w   h   w   w   w   h
It does not matter which note you start on to build the scale as long as the intervals stay the same... Say you want to play an E major scale... Then make the E the first note, and just keep the intervals between the notes the same.
1   2   3   4   5   6   7   8(1)
E   F#  G#  A   B   C#  D#  E
  w   w   h   w   w   w   h
Now that we've learned how to build a major scale..how do we build chords? Chords are built by playing a combination of notes in relation to the major scale... this is why you have to know the major scale! For example... major chords are built by using the first, third, and fifth notes of the major scale... Cmaj = C, E, G...Emaj = E G# B the numeric formula for a major chord is 1 3 5 Make sense? Each note within the chord plays a role..the 1 obviously names the chord..it is the root, the 3 defines whether the chord is major or minor. If we want to play a minor chord, we simply shift the third down a half step, or we "flat" the third, or in technical terms, we play a minor third... the formula looks like this 1 b3 5
Cm = C Eb G        Em = E G B
To play some more advanced "jazzy" chords simply add other notes, the most common chord "embellishment" is to add the 7th scale note to the chord formula... Now understand there are 2 different names for the 7... There is the major 7.. Which is the true 7th tone of the major scale, and the dominant 7... Which is a b7 In a chord chart you will see them written like this
major 7            maj7       formula = 1 3 5 7   
dominant 7          7         formula = 1 3 5 b7
You may see some chords with higher numbers such as 9, 11, 13 for those you only have to know that once you reach number 8, the notes of the scale start over, only an octave higher... 9=2 11=4 13=6
                     1  2  3   4   5   6
1  2  3  4  5  6  7  8  9  10  11  12  13
C  D  E  F  G  A  B  C  D  E   F   G   A
One more quick thing, then we'll get to some reference charts. If you have ever seen a chord like D/F# or A/C# and scratched your head..your worries are over, I'm going to explain those..the first letter is the chord name, the second letter is the bass note....so rather than playing the root note as the bass note, you play another chord tone as the bass note... example...D/F# or D/A
e--2--  F#  3rd             --2--  3rd
b--3--  D   Root            --3--  Root
g--2--  A   5th             --2--  5th
d--0--  D   Root            --0--  Root
a--0--  A   5th             --0--  5th
E--2--  F#  3rd             -----

on the double flat 7..you drop it back 2 half steps and play the 6th note of the scale. a couple other common chords that don't really fall into any of these catagories..

5(power chord)              1  5
here is a chart of some moveable chords shapes... Play these shapes anywhere up the neck and the note on the 6th string is the root. In all examples the root is on the 3rd fret 6th string or the G note.

In case you are having problems understanding how I wrote the chord chart... Let's look at the Fmaj7...xx3555 The first x represents what you play on the 6th string or low E(x means don't play)... 2nd x is the 5th string, the 3 means you play the 3rd fret on the 4th string... And so on... This is by no means all of the chords shapes that are possible, but it will get you started with some advanced voicings, and you should be able to start building your own voicings of the chords as you see fit... Experiment with some of the chords here...take a simple chord progression that you already know and if you play a major chord, try substituting it with one of the chords from the list of major 3rd chords... If it's minor, play with some chords from the minor 3rd list, and if it is a dominant 7 chord... Grab a chord out of the dominant list... You'll get some really interesting sounds... I apologize for not listing open position cowboy chords or major, minor barre chords, but i figure most of you already know that, and I had alot to cover. As always, feel free to ask questions or post comments Hope this is helpful Have fun with your newfound knowledge.
