Songs based on a simple rhythm and few chords can be interesting in unexpected ways. I think Springsteen's
Streets of Philadelphia and
Missing are perfect examples of that.
This brings me back to many years ago (pre-computer era) when I saved and partially borrowed a couple of hundred "Gulden" (nobody here in the Netherlands had heard of Euros just yet) to get me an Alesis Drum Computer.
The rhythms were inspirational and I came up with a couple of concepts that, in retrospect were more interesting than some songs that involved more complicated chords/arrangements.
Back to your song Robert ;-)
You've achieved something very interesting here. Well done!
There's probably more where this came from? Feel free.
