• Now you can play big chords without having to memorize anything

    in Chords & Progressions

    stackinglarge.jpgOn yesterday’s radio show, I got a question from a fellow in Vallejo, California about polychords.

    So today, I just want to take a second to explain what polychords are for those of you who missed the show.

    First, it’s helpful to note what the word “poly” means.

    It’s a greek prefix, meaning “many” so that should give us a hint as to what polychords are.


    And that’s exactly what a polychord is…

    It’s usually a bigger chord that consists of two or more smaller chords, one on top of the other.

    You can also refer to this as “stacking” or “superimposing” one chord on top of the other.

    So it really is that easy.

    Let’s explore some examples:

    What happens if you play a C major triad on your left and a G major triad on your right?

    (C + E + G) + (G + B + D)

    That’s basically stacking the 5-chord on top of the 1-chord.

    Note: Since both chords have a G in it, you can choose to either use the left hand or the right hand.

    Left hand: C + E Right hand: G + B + D

    Left hand: C + E + G Right hand: B + D

    (This chord is still not that huge so you can play it all with one hand: C + E + G + B + D).

    This is a C major ninth chord.

    C + E + G + B + D
    1 + 3 + 5 + 7 + 9

    What if you changed all these chords to minor?

    C minor on left and G minor on right?

    C + Eb + G + Bb + D
    1 + b3 + 5 + b7 + 9

    This is a C minor 9 chord.

    What if you played a C major triad on the left hand and a Bb major 7 on the right hand?

    So that’s basically the 1-chord + b7 chord (“flat seventh chord“)

    C + E + G + Bb + D + F + A
    1 + 3 + 5 + b7 + 9 + 11 + 13

    Wow! This is a huge chord. A “C13”

    So basically, polychords are composed of smaller chords stacked on top of each other. Regardless of whether you’re playing a ninth, eleventh, or thirteenth chord, they can always be broken down to smaller chords because all of those extended chords are essentially polychords.

    Why is this important to know? Well, for one, if you’re playing with a bass player, it’s helpful to know what you can play on your left hand and what might work well on your right hand. Then you can start inverting chords on either hand to make different combinations. From there, you can start altering chords and now you’ve just entered the world of “two-hand” altered chord voicings. It’s crazy indeed!

    Rather than me continue to spoil things, how about we use the comments section below to come up with more polychords.

    Here are some formulas. You can pick any key you want…

    1-major + 5-major = 1-major 9 chord

    1-minor + 5-minor = 1-minor 9 chord

    1-major + 5-minor = 1-dominant 9 chord

    1-minor + 5-major = 1-minor-major 9 chord

    1-major + b7-major = 1-dominant 11 chord

    …And the list goes on —

    I’ll start the exercise off in the comments. Post any key you want!

    I hope you enjoyed this lesson.

    C major:

    C major + G major = C major 9
    C + E + G + B + D

    C minor + G minor = C minor 9
    C + Eb + G + Bb + D

    C major + G minor = C9 (also known as C dominant 9… works great on the 2-chord right before progression to a 5-chord in a “2-5-1” progression)

    Who else wants to add to this list in another key?


    Bb MAJ9

    Bb MINOR 9TH

    Bb DOM 9TH

    Bb min MAJ 9TH

    Bb DOM 11TH

    I appreciate the examples you have here. But one question on the last one:

    Bb DOM 11TH

    Is the A really or is it supposed to be Ab, I feel that I have not understood the whole dominant (DOM) part of it. I thought that any time you see DOM it means the 7th is lowered?

    Thank you for any feedback you may give me.

    G major 9
    G + B + D + F# + A

    G minor 9

    G + Bb + D + F + A

    G 9

    G + B + D + F + A

    G min maj 9 ????

    G + Bb + D + F# A ????

    Thanks for this great info. By thinking in terms of all these chords as ” 1 chord plus 5 chord” i was able to call them up really fast. great help.

    @Ray: You right on the money doc!

    So did breaking up the chords into smaller ones really help to know them faster?

    E major

    E major + B major = E major9

    E minor + B minor = E minor9

    E major + B minor = E dom9

Please don’t buy into the hype and misinformatoin that you’ll make a ton with your very first website… anything’s possible, but that’s highly unlikely. You can, though, find any number of ways to make some cash online.

    I’m a beginner but I just realized to play a 7 in any key you take the whatever note is in the bass and play the chord associated with the third tone of that scale. Example

    Key of c

    C major 7 = C in the bass over E minor
    D minor 7 = D in the bass over F minor
    E minor 7 = E in the bass over G minor.

    It works in every key.

    Hi Germaine,

    This is the best explanation about polychords I´ve ever read. Keep up the good work!

    Hi Jermaine,

    Sorry but I think you made a mistake.
    When you say 1-major + b7-major = 1-dominant 11 chord, isn´t it a 1-MAJOR 11 chord?

    Sergio Kokitsu

    23 Jermaine Griggs


    The b7 (aka – “flatted 7th”) is what you’re playing the major chord on, not the major 7th. So in the key of C, this would be:

    1 major (C major) + b7 major (Bb major) = C dominant 11

    (C + E + G) + (Bb + D + F) = C dominant 11

    C major 11 would be: C + E + G + B + D + F and the formula would be:

    1-major + 7-diminished = C major 11


    1-major + 5-dominant7 = (C + E + G) + (G + B + D + F)

    Of course, G is same note so you’d only play it once.

    24 Sergio Kokitsu

    Hi Jermaine,

    Thanks for the explanation. I was confused about b7-major, because I was thinking it as 7-diminished.
