You can learn how to play the open position Gm chord and CAGED Gm shape!
The open position Gm chord is not very common at all, extremely few songs, if any, actually use this chord. I use it when I play Starman but David Bowie didn’t.
This is a chord I discovered through understanding the CAGED system.
This was an extremely important discovery as without having 5 positions of chords, just like we have five positions of the Minor Pentatonic, we can’t fully understand the fretboard.
Isn’t it strange that nobody ever used the open position Gm chord in the history of famous songs?
As a moveable chord shape, it’s a bit stretchy and doesn’t really work. Let’s look at how we can extend it as it then becomes just as good as all other CAGED chords.
Gm chord extensions
We can’t extend to any 9 chords as a 9 would only be possible on the same string as we have the m3rd.
These are all possible Gm-shaped chord extensions.
- Gm chord (root, 5th, m3rd, 5th)
- Gm7 (root, m3rd, b7, root)
- Gm7b5 (root, b7, m3rd, b5)
- Gdim7 (root, b5, bb7, m3rd)
- Gmmaj7 (root, m3rd, 5th, 7)
- Gm6 (root, 6, m3rd, 5th)
- Gm11 (root, b7, 9, 11)
It’s a great start to just play all these chords, and try them all out, but it won’t be enough.
In order to fully understand them, you must relate them to songs or you won’t remember their unique sound.
I’ve mentioned Starman earlier, the first chord of the verse can be an open Gm chord.
Gmmaj7 is extremely unusual but perhaps the easiest of all chords to remember once you played it and thought of James Bond.
Ain’t No Sunshine uses a Gm-shaped Am7 chord for the 2nd guitar.
Building scales and arpeggios around the Gm chord/shape
You can play a min7, and min7b5 arpeggio by first visualizing the Gm chord shape, then filling in appropriate intervals around it.
The same goes for Minor pentatonic, simply add all intervals.
Once you have your Minor Penttaoic framework, you can build all remaining minor scales.
- Blues, add b5
- Conspirian, add b5 and maj7
- Dorian, add 2 and 6
- Aeolian, add 2 and b6
- Phrygian, add b2 and b6
Here’s a diagram that shows you all this.
There are exercises to practice all this in the SEPR, a module you get when you sign up for my guitar courses.
In the courses, we play and learn from songs. Part of that is to move the chords, melodies, and licks around the fretboard, always trying out all shapes.
Doing this will teach you how to play in this Gm shape in a musical way. Only playing exercises won’t do that.
You have a few stages to go through here to master this shape.
- Play the Gm shape as an open position chord
- Make it a moveable chord shape
- See all the intervals in the chord shape (root, 5, m3rd, 5)
- Extend to all possible chords
- Build the two arpeggios
- Build all scales
- Try them all in songs
The final point is the most important.
The guitar courses are all about building great habits so you in the end can do all this straight away with any new song that you come across.
I hope to see you in there so we can get to work on the Gm shape and all other CAGED chord shapes.

This is the foundation upon which we learn to extend chords and build arpeggios and modes as well.
