    Hi Mark,

    Great lessons as always, your really helping me understand music theory more than any other material I use.

    Just wanted to ask one question; when playing a minor third I always use my fourth finger 3 frets up from the root rather than the way you use by shifting up a string and back 2 frets. I find this easier as I don’t have to move my hand around as much.

    Is this a good way to play a minor 3rd or will this cause me any issues further down the line of learning more music theory?

      Thanks Ben. You’re absolutely right to learn the minor 3rd pattern that way but it’s also important to learn them on one string too. For every interval there are at least two common ways to play them and they also tie into the 3 scale shapes I described in my Tri Shape lesson. Learn each interval going up the neck and also going down the neck. So a 3rd (major or minor) can be played on the same string as the root going up the neck and also on the neck string up going down the neck. The fourth is mainly played in one way but then the perfect 5th can be played 2 frets up on the next string or 3 frets down, 2 strings across eg. root C on 8th fret of E string and G on 5th fret of D string. Learning each interval shape in this way helps to see intervals within all types of lines more clearly.

    Great lesson. However, it would be nice if you covered the fingering you like to use for these arpeggios. It’s hard and tedious to pick it out from the video as you go over it so quickly. Do you always use the same fingering going up as you do coming down? For example the C-Major 9, it looks like your fingering is 1-2-4-1-4. What’s the fingering coming down? I don’t see it in the PDF either. It was useful when you included the fingering in the 7th chord PDF. Thanks Mark!

    Great lesson Mark. You make the extended chords simple to understand compared to other on line sources and books. Thanks again.

    Mark, thanks for a great lessons!!

    I understand how to build a chord extensions, but how we may apply them? For example, if we play on a guitar maj7#11 chord that is IV (lydian), how will sound such note as perfect 11? We should play #11 as I think, because it will sound more harmonically. And m7b13 chord, that is VI (natural minor)? In this case, I should have played b13 instead of perfect 13.

    Hi Mark, I was taking a look at the lesson material for this video and I have found a mistake in the C7 extensions. C7 is tabbed correctly, but C9/11/13 all have the 7th scale degree raised causing them to be major.

    Top ten lessons, Mark on The Chord Construction series. It’s helped me big time to see through the mist.
    A million thanks,
    Bob Eberlein,

    Hey Mark, I just wanted to let you know there is a mistake in the transcription for the Example 3 (Extensions of C7). The bass tab shows Maj7 instead of Dominant 7. Thanks!
