SeeChord is the name of a project I am working on that can display chord progressions and harmony in music.  The idea just landed on me in its complete form while I was teaching piano, and refused to go away.  I was convinced that the idea must already be “out there” so spent a few days researching and found that nobody had ever done this before.  A US Patent, registered design and website ( ) later and now seechord is taking on a life of its own. Here is my youtube tutorial.

My aim with SeeChord is to enable students, teachers, song-writers and musicians to access the complicated world of chords and harmony at a much higher level than is currently available.  With a very small amount of training, SeeChord can be a very powerful tool, x-raying a piece of music and revealing the often beautiful structure of the harmony.  Here is an animated extract from Bohemian Rhapsody that shows how to interpret a chart.

    You should really release a tool for arranging seechord charts as open source….

  2. Appreciate it for helping out, wonderful information.

    Dear Joe
    I thought i would contact you to say how much I enjoyed your site and
    to share something with you that i use in the classroom to teach
    harmony and writing of chord sequences that you might have heard of or
    be interested in. I call it the chord class system ( circle of fifths
    in disguise),. This is how it works.

    3rd class (chords divisible by 3) 2nd class ( chords divisible
    by 2) first class and Tonic Class
    vi iii
    ii and IV V & vii I
    in C am em dm
    F G bdim C

    Rule is that chord I can go anywhere but then the chords should stay
    in their class then follow in order of the class system not jump over
    classes- the exception being that chord IV which can jump over first
    class ( plagal cadence)

    ie I IV I ii V I iii vi ii vii V I etc This works
    extremely well when working out which chords should harmonise a Bach
    chorale – write down possible chords with each note – ie tonic = I IV
    & vi etc and then plot the Bach route through the chords using the
    class system

    Once students are able to compose a chord sequence using the class
    system they can then create the surprises – like you suggest I IV
    V IV (breaks rule) V vi ( breaks rule – interrupted) or repeating
    part of a sequence and delaying the cadence – making the ii to II
    (major version) can then help modulate to dominant or iii become III (
    major ) to help go to relative minor ( which then becomes the new I)
    ie: I ii V ii (breaks rule) V ii V I

    I like your sidewise moves too through tritones falling chromatic
    Dm Db7 C
