Sus7 Chromatic Climb

Here's a little chromatic thing I stumbled upon one day at the piano. I like it because you get the smoothness of chromaticism (obviously), but also variety via slightly different chords.

The chords here alternate between a sus-7-with-9th and a sus-7-without-9th.

That 9th or 7th in the top voice in itself creates a satisfying shape and is a nice contrast to the straightforward half-step climb in the lower voices.

Here it is with the voices separated, which makes it easier to notice some of the intervallic relationships between each voice. In this image, I described each voice's movement and made note of each voice's relationship to the bass.
