Leaving the roots out 

This following focuses on rootless drop 2 minor 9th chord positions. Because it is not always possible or easy to include all chord tones when you play 9th chords, you have to leave some chord tones out. As it is the case here, the root is ommited.

Please note that it is important to locate the root even if it is not played. This will help you find more easily the chord position on the guitar neck and as well as its name.

The construction of minor 9th chords can be based on drop 2 minor 7th chords. It's quite easy, you just have to replace the root with the ninth. Here are two guitar diagrams that show the relation between these two chords.
