Harbin has its ways, - what is the code here? It's pretty hippie, and has been so for a long time now. No one is in charge, and it just kind of meanders along. No one is in charge? Oh my, ~ it's kind of like nature or ecology :). But it has attracted an interesting group of people, who run it behind the scenes.
Music - Why do we like sequences of tones? What could have selected for this appreciation, evolutionarily?
And from these notes, for example, do re mi fa so la ti do, and octaves around them, we can shape infinite numbers of lines of music. Wonderful!
