Improvisation With 4th and 2nd Interval Stacks

Improvisation With 4th and 2nd Interval Stacks

This is a continuation of last week’s free lesson blog, where we talked about stacking 2nd and 4th intervals.

Improvisation with 2nd and 4th interval stacks

Check that blog because it tells you how to practice what we are about to cover today.

Today we are going to have a look at 42. (stacking a 4th and a 2nd)
As discussed in last week’s blog, these are quartal harmony chords.

44 is root position
42 is first inversion (mostly sus4 chords)
24 is 2nd inversion (mostly sus2 chords)

In the key of C, the chord tones for all 7 chords you get when stacking a 4th and 2nd, are:

C F G – Csus4
D G A – Dsus4
E A B – Esus4
F B C – 1 #4 5
G C D – Gsus4
A D E – Asus4
B E F – 1 4 b5

As you see, 5 out of 7 chords in a major scale, when stacking a 4th and 2nd, are sus4 chords.
There’s not really a chord name in music theory for the chord on IV (F B D) and VII (B E F)

If you studied or read the above free lesson blog first, then you know all you need to know, including how to practice this.
All we still need to cover at this point is the 42 shapes.
Here they are on every string set:


Hit me up anytime at if you have any questions, or if you would like to book a lesson.

The free lessons I offer on my blog are cool, but you will never experience the progress, joy, and results that my students experience in lessons when you’re learning by yourself from blogs and videos.

That is why people take lessons: way better results and progress, much more complete information, exposed to way more creative ideas than you can get from a blog or YouTube video.
There is only so much that self-study can accomplish.

If you want to see amazing results and progress in your guitar playing, buy your first lesson here and get started ASAP.

  • 1 Lesson = 75

You’ll impress your friends and loved ones in no time with your guitar playing!
