• Here’s a quick and easy refresher on tertian chords

    in Chords & Progressions

    As you may know from past lessons, tertian chords are built on thirds.

    This is majority of the chords you’ll play since almost every common chord (like major, minor, dominant, diminished, augmented, and even most altered chords) are built on thirds.

    In this post, I wanted to provide a quick refresher on some of the most common tertian chords.

    C major

    C minor

    C diminished

    C augmented

    C major 7

    C minor 7

    C dominant 7

    C# diminished 7 (my image program doesn’t do “double flats” so I’m going to put the C# diminished 7 below). Note: The C diminished 7 chord is C + Eb+ Gb + Bbb (aka – “A“)

    C half diminished 7

    C augmented major 7

    C augmented 7

    C major b5 (flat “5”)

    C minor major 7

    C dominant 7 (b5)

    Print this chart out! You may need it some day!

    well,im not sure if the C diminished 7 chord is like was written above .
    i know that the right chord is : C,Eb,Gb,Bbb – and you wrote : C,E,G,Bbb (i mean
    where the “note” part is above ) .

    What i did above was C# diminished 7, not C diminished 7 since my graphic program doesn’t do double flats yet. :-)

    i agree with tal..
    this part “Note: The C diminished 7 chord is C + E + G + Bbb (aka – “A”)”
    should be “”Note: The C diminished 7 chord is C + Eb + Gb + Bbb (aka – “A”)”

    You guys are right. I didn’t notice the note underneath. Corrected.

    Helpful information. Lucky me I discovered your site accidentally, and I am surprised why this twist of fate did not happened in advance! I bookmarked it.
