I'm caught up with Stormlight. Does it mention somewhere what the "note" is and I just missed it? They use the violin bow + metal board with sand early on to show the discuss the concept of patterns in the world. I didn't know if Sanderson said if he had sound in mind that produced the mapping of the Shattered Plains. I feel like it would have to do something with Stormseat and the Oathgate since they reside in the middle of the Plains.

Has Sanderson ever stated whether or not there is a specific tone/sound he envisioned the layout of the Shattered Plains resembles?
