Extended chords obviously contain more notes than triad chords.
It is also common practice to leave out some of the notes. If you wish to learn more about this, there are many advanced music theory sites to explore on the internet.
Here, we are only focusing on examples that are relatively easy to play and are moveable (generic) across the fretboard.
The diagram below shows 2 examples of the A minor 11 chord plus the generic minor 11 shapes.
The indigo note is the root note of the chord, for example:
– if you wish to play the G minor 11 chord then the indigo root note will be the note of G,
– if you wish to play the E minor 11 chord then the indigo root note will be the note of E, and so on.
