Eb Minor Ninth chord (Ebm9) on the guitar fretboard

The Eb Minor Ninth chord (Ebm9) is made of Eb (the root), Gb (minor third), Bb (perfect fifth, optional), Db (minor seventh) and F (major ninth). The fretboard shows every one of them across the neck in standard tuning (E A D G B E), and plays them back so you can hear the chord.

The minor ninth is a minor seventh with a ninth stacked above, and the fifth is optional. Its notes repeat in several overlapping shapes on the neck. It sits between the minor seventh and the minor eleventh.
