    The basic funda of chords(as Vini kindly put it) :

    Each note of the major scale corresponds to a chord. Seven notes=seven chords.


    1st note- The root of the scale. Major chord.

    2nd note- Minor chord

    3rd note- Minor chord

    4th note- Major chord

    5th note- Dominant seventh chord. May also be played as a major chord but the family remains dominant seventh

    6th note- Relative minor. minor chord. The natural minor scale of this note is the same as the major scale we are talking about right now.

    7th note- Half Diminished chord or Minor7th flat5th. Not a lot of guys mess with this.

    So for the C scale-

    Notes: C D E F G A B

    Chords- C Dm Em F G7 Am Bm7b5

    Relative minor- A

    Am scale- A B C D E F G


    For further info look up zings new thread in the guitar tips section.

    @vini
    a chord family is a set of chords that exists together harmoniously - these chords are derived frm the scale of the song

    if u take E major scale --> E F# G# A B C#D#
    so E-A-B are the first, fourth & Fifth notes

    likewise D major scale --> D E F# G A B C# --> again the first, fourth & fifth

    these r the most common family/progression & r usually called I-IV-V chords
    there r other common progessions - most of the songs wil fit into one or the other of these progressions
    I-II-IV-V
    I-II-VI-V
    I-III-II-V
    I-III-IV-V
    I-III-VI-V
    I-VI-II-V
    I-VI-IV-V

    the tonic, dominant seventh and subdominant is a good way to start. i remember dan morgan's book where this is referred to as the "three-chord trick" :)

    To add to this, what happens if we jump scales. For example....in a chord progression, what if we suddenly have a D major in our progression which was earlier in the key of C major?


    When a situation like that arises, we find that we have two or three different scales that might fit with the chords...eg, lets take this progression.


    C Am F G

    and from the bridge you go to a progression like

    F#m Emajor F#m E


    Now the problem with this progression in the bridge is that it could fit into two different scales. These two chords could be the Root and 2nd of the E major scale or they could be the 5th and 6th of the A major scale....so which scale can we use here.

    Technically we can use both. However, since we've just played in the key of C major before this, the scale which is closer to C major in terms of the number of sharps or flats in it is what we shall choose.


    The key of C has 0 sharps.

    The key of E has 4 sharps...F#, C#, G#, D#

    the key of A has 3 sharps...F#, C#, G#

    therefore using an A major scale on the bridge will always sound better.



    So the trick to jumping scales is to try and use the scale which is closest to the earlier scale in terms of sharps and flats.


    Feel free to ask questions.

    what are relative minor scales? How can we find one for a given scale?

    I think its the minor scale with root note 3 semitones below the major scale
    eg for Cmaj it is A#min
    Somebody correct me if im wrong

    not really. a relative minor starts from the 6th note of the major scale. so for C major, it will be A minor.
    basically, they are the same scales, but the starting note is different.

    Just had a brainwave when i was in toilet, duznt it melt down to circle of fifths? Here:

    Code:
           C
       G       F
     D           A#
    A             D#
     E           G#
       B       C#
           F#
    
    Just skip two major notes, and u have the relative minor. Is it right?

    @Johny Bravo, you have drawn the COF the other way round.

    @sayanakaharry, @ambush is right when he says the relative minor is 3 semitones below the major. Its exactly the same as the 6th note in the major scale. Both of you are correct. Some prefer @ambush's style while others prefer to remember the 6th note formula.

    There is nothing called CHORD FAMILIES. There are just CHORD PROGRESSIONS in a scale.

    well
    ya its two ways of lookin at the same thing, but....

    that was what i wanted to correct actually.

    @iprakash: Really? Nah man i think its ok. I have always seen it this way. R u sure? Plz post ur version. Maybe i am wrong.

    @sayana, good correction. I overlooked it. Was concentrating on the theory ;)

    @johny, In the COF, as we go in the direction of the clock we go up a fifth and counterclockwise we go down fourth. Your version may be called the circle of fourths :)

    Anyway, The circle of fifths is this:

    Code:
    [COLOR="Blue"]
           C
        F       G
     A#           D
    D#             A
     G#           E
       C#       B
           F#
    [/COLOR]
