The Benji Pad

This is a easy two-chord drone. The second chord may look complicated, but it is just an Ab major 7th with a D natural (#11) and that chord is played with a Bb in the bass. For purposes of improvising, don’t worry about the Bb. Just play Ab major and raise the Db to a D natural. 

And considering that those same notes work for the C minor chord as well, you really just need to play in three flats the whole time. Like I said: easy.
