Minor 9th chords
The Minor 9th chord is easy to memorize if you are familiar with the 9th Chord. The difference is that one note is lowered (on the 4th string), which results in a longer stretch. The 1st and 6th strings are marked with "x" (teh 1st string can be played, but it makes the chord more difficult). If we compare C9 with Cm9 we could see that the notes changes from C, D, E, Bb to C, D, Eb, Bb.
Notice that the shapes are the same (notice also the irregularity for Bm9). This means that the chords are movable and, therefore, you can easily find out how to play C#m9 /Dbm9, D#m9 /Ebm9, F#m9 /Gbm9, G#m9 /Abm9 and A#m9 /Bbm9 as well.
