Thank you, Tom! I have this and Verloren 1 downloaded to my device, and have all the oords 1-15 in order on a playlist, so I can leave them on infinite loop. (I did include 13, but I see what you mean, it does sound very similar to 10). Anyway, it creates a serene backdrop for reading, meditation, or even sleep (that's a compliment - if music can put me to sleep, I really like it! If it keeps me awake, then I usually find it kind of jarring).
