Starting with the thought of comforting noise, I had decided to focus on using filtered pink noise as the basis for the piece. Woke up with a dream of someone playing this little melody on the piano, so that had to go in, too. The piece opens with two streams of pink noise, separated by an octave (like parents, maybe). Those I generated in SuperCollider (will put code in comments). In Logic I added piano, synths and percussion and mixed the tracks.
