It is a little confusing to me why this melody haunts me, maybe there is an underlying predictability or drone that I can sense.  I added the RCSB coloration and single letter designation for the amino acids. The colors are slightly representative of the relative acid and base tendencies of the amino acids. I am not sure what the colors represent in other than in those four AA where those properties are more pronounced like acid and base qualities.  This is shown in the image on the right.

I would love to add a base or snare where the glycines occur… as those notes are relative low on the tone scale of the audio ( and it is a lot of work to go back and identify the glycines — of which there are many many.

Just an experiment, just a learning experience for me, no promises of absolute accuracy but pretty darn close.
