Chord Building 101

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..

sus2                        1  2  5
sus4                        1  4  5
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.

Very helpful. Thank you very much.

[animesh_joshi]

One of the best articles I've read so far on Chords

[dma529]

Great article. It's very clear and easy to understand.

[dma529]

Sorry about the double post but is the Gmaj7 wrong in the movable chord shapes? Shouldn't the notes be G-B-D-F#?

[hounddogmusic12]

dma529, you are right about the notes in the Gmaj7 chord, but the shape is right...
e--x--
b--3-- D
g--4-- B
d--4-- F#
a--x--
E--3-- G

[dma529]

Oh right, sorry it was like 3 in the morning I don't know what I was thinking..

[hounddogmusic12]

no prob...happens to all of us

[libertines4ever]

nice that you mentioned the 9th 11th 13th was an octave higher
some articles forget to mention that

[BlaqIc3]

good stuff.....good stuff indeed. TY

[Music=Life.]

Thanks!

[flxjhnlrssn]

Good article, ive read a few about this before but havent really understood it untill now, thanks

[Blas3]

good one!

[HannibalX]

AMAZING LESSON!!! Kudos!

[Niskat]

really great lesson, dude!
just one correction:
"dim7 1 b3 b3 bb7"
shouldnt this be "1 b3 b5 bb7"?

[hounddogmusic12]

yes it should niskat...must have been a typo...thanks

[ainokeabrah808]

hey i have a question. and i hope it doesnt seem stupid, but for major chords like you were saying. its the 1st, 3rd and 5th. so for example Cmaj is C E G. I got that. but how do you know which string to start on and which ones to use?

[hounddogmusic12]

ainokeabrah, there may be an easy answer to your question, but sadly, i do not have it...the best thing that i can tell you is to learn the open position "cowboy chords" along with the different barre chords...also check out my 2 lessons on triads, there is some really good info in them about chord shapes...you can take the triad shapes and add other scale notes to them to make some of the more advanced chords....if you are playing single note arpeoggios, then it really does not matter which string you play which note on...you can play all the notes on 1 string if you want to, whatever sounds good to you is right. i know in the lesson i said the 9, 11, and 13 are an octave higher than the root, but it really does not matter where you play them, they can be a lower tone than the root and it will still function the same way, but once again, let your ear guide you. hope this makes sense

[hounddogmusic12]

most of the time when you strum a chord, the lowest tone is the root, in the open position C major chord, the lowest tone is the C note on the 3rd fret 5th string...but that is not a concrete rule...you can play different "inversions" of the chords...in the above examples the inversions of D are D/F# and D/A...where you just play another chord tone as the bass note...in the C major chord the G note is the 5th so you can play that as the bass note by adding the 3rd fret 6th string to the open chord and you have C/G 332010

have i confused you now?

[ainokeabrah808]

haha yea you did. Well i know the chords already i've memorized them before. i was just wondering how you know which strings its on. but i think i understand it a little like how you can use any string.Thanks man

[iFire]

I never understood the scale chord theory until you explained in that one line. Lol. Make so much more sense now. Ty, I vote for more guides from you!

[jurgh1]

interesting article. now i know why the fingers are placed excactly where they are, when i play a chord thanks hounddog!

[Gods Guitarist]

Wow. This really helped clear things up for me! Great Lesson! You should write a book or something!
JK

[Daniel_xz]

dude you rock thanks a lot i always had problems with understanding that now i think im finally enlightned xD

[SteveHeyn]

Amazingly helpfull. Really I don't think there is any chart out there on the web that covers that much practical info on one page.

People who don't understand theory will appreciate this a lot.
Theory was well explained tough.
No insult to the people who don't know how to play Cmaj (or just C) - go back to basics. Take a beginners guide for guitar and start learning al the notes on the first 3 frets of all 6 strings. If you can play those without thinking you should have a good base to start. If that doesn't work out try at least to memorize the positions of CDEFGAC (Cmajor scale) WITHIN the first 3 frets of the neck. You'll finf yourself with using only 4 strings. After that extend the scale to EFGAB-CDEFGAC-DEFG (still within the first 3 frets of the neck) once you can do that just fill in all the sharps between them. Remember that there is only a half step (so no flat or sharp) between E and F or B and C !!! Basicly an E sharp IS and F and vice versa a F flat is an E.
For al other intervals for exaple A - B there is a sharp (A sharp [A#]) in between.

[SteveHeyn]

A sharp = A#
B flat = Bb

and big magic:
A# = Bb
A sharp = B flat

there is NO E# Fb B# or Cb
if you see them they mean F E C and B.

rock on!

ANYTIME

[SteveHeyn]

oh, and don't confuse flat with minor
don't confuse sharp with major

those thing are different.

Maybe i'll post my own comment, feel free to email.
