What is this?

A unique chord progression that sounded rather mysterious to me. It doesn't make a lot of sense technically, and maybe it doesn't have a clear feeling, but I like it.

Damp Cavern

My first recording. I think this was just the second take and I usually am too lazy to take a gajillion attempts and so I just settled for this one. There are a few noticable mess-ups but whatever. This is where I started.

playing some 7th and 9th chords in the 2nd inversion and improvising overtop of that with my right hand by tapping to create a melodic line.
