• 3 simple ways to use diminished seventh chords

    in Chords & Progressions

    The diminished seventh chord can come across as scary (and it certainly has its place in horror flicks) but there are actually quite a few usages for it.

    In this post, I want to talk about different ways to use the diminished seventh chord in real-life situations.

    1) Use a diminished 7 chord as a transition to any 2-chord.

    As you know from past lessons, the 2nd tone of the scale is usually minor. It has a strong pull to the 5th chord. Thus, where we get the name “2-5-1” progression.

    Well, you can use the diminished 7 chord a half step lower than the 2 chord as a nice little transitional chord.

    Let’s try it in the key of C major…

    C# diminished 7

    D minor



    2) Use a diminished 7 chord on the 6th tone of the scale (also takes you to a 2-chord).

    Alternatively, instead of playing C# as your bass on the first chord, you can use “A” (which is the 6th tone in the C major scale). This also has a strong pull to “D” (see prior lessons on the “circle of fifths“.)

    With the “altered bass,” this gives you an A7 (b9) chord (a.k.a. – “A dominant seventh with a flatted 9”)

    A7 (b9)

    D minor



    3) Use a diminished 7 chord in between a 4-chord and 5-chord.

    This happens a lot in blues and jazz. A song will go to the 4-chord and follow up with a diminished 7 chord a half step higher… which usually leads to a 5-chord.

    Here’s an example in C major:

    4-chord: F dominant 7

    #4-chord: F# diminished 7 (sharp 4)

    5-chord: C major / G (a.k.a. – “6-4 chord“)

    Note: Sharps and flats are mixed intentionally. This has a lot to do with properly naming chords. See these two lessons for details).

    Exercise: I’ve started you off with 3 scenarios. Where are other places you use diminished 7 chords? Let’s try to make a nice little list with examples.

    really liked this quick lesson. I gotta practice these


    2 Roland

    We might make use of it going around the circle,as from a previous lesson.
    i.e. starting in key of C:
    C maj7 C/B E
    C#dim7 C#/Bb E G
    Dm7 D/C F
    G7 G/B F
    Cmaj7 C/B E
    New key Bb
    Bdim7 B/Ab D F
    Cm7 C/Bb Eb
    F7 F/A Eb
    Bbmaj7 Bb/A D
    etc. etc. around the circle


    3 Roland

    As dominant function chord (Bdim7) leading to the Imaj9 chord.

    Cmaj7 C/B E
    Dm7 D/F C
    Bdim7 B/F Ab B D
    Cmaj9 C/E G B D
    Cm7 C/Eb Bb
    Adim7 A/Eb Gb A C
    Bbmaj9 Bb/D F A C
    Awesome sounding progression!

    Diminished 7th chords make great arpeggios (even bassline and keyboard runs), try and see. TIP: Takes Practice.

    Very informative lesson, Jermaine. Could you explain the 5-chord (G) above? I cannot understand why you have C.E.G in the right hand. I was able to follow the other chord constructions.
    By-the-way, what is that Ab minor 7th chord above? I am lost on that one!


    7 widmarck francois

    That is some great lessons but it would have better if they were demonstrated in a song and on a video.Thank you!I like it anyway.


    8 connie

    You have lots of things to teach, and lots of people to benefit. I feel though, you take a long time to make a point, and you lose attention from mere attrition ! Good bye and thanks.

    Could you please post something on Quintal Chords
    We are forever grateful for your continual support

    Awesome post. I feel like I can finally wrap my brain around the concept of diminished chords. I knew what they were and how to find them but this post really solidifies it in my mind in a way that I can immediately implement. Thanks Jermaine!
