This way you can start with memorizing the shape and chord name based on a chord shape you already know. These shapes are also moveable, like a bar chord, so shifting them around will help you play them in other keys. I'm going to show them in E bar shapes and A bar shapes so you can have a few different places on the fretboard to play them.
9th Chords:
Here are the notes that are included to build these chords and their names:
Chord | Name | Chord Structure |
E9 | 9th | 1, 3, 5, ♭7, 9 |
Em9 | minor 9th | 1, ♭3, 5, ♭7, 9 |
Emaj9 | major 9th | 1, 3, 5, 7, 9 |
Eadd9 | add 9 | 1, 3, 5, 9 |
Rather than focusing on the theory of the chord, which is included above in the chord structure, I want to focus on learning the shape. This will help you remember it and add it to your chord vocabulary.
