That would be the Alberti bass talking. Pick a minor key and a slowish tempo, arpeggiate a chord in the left hand while you have a relaxed single-line melody in the right, do the aforementioned production tricks, and you've got the effect you're looking for. Go for simple chord progressions: i iv i V kinda stuff, repeat. Just working really quickly, I made four examples in four different keys in four different meters: http://www.mediafire.com/?x6hnrngk6ekxlh1 I didn't do anything with the audio, this is just Finale's sounds. Out of all four of those, the first two are good, the third has its moments, and the fourth kinda sucks. I'm following the same procedure for each of them, which is arpeggiated accompaniment figure plus a simple melody. The last two, I put the accompaniment in the right hand. You can hear how much better it sounds in the left hand when it switches over in bar 32. The third melody, at bar 17, sounds better with the accompaniment on top, but it's in minor, the melody is also better, and there is more separation between the two layers. Anyway, the point is that this is an easy texture to put together. Try making some yourself now.
