While reading about unusual guitar techniques, I found this article on Wikipedia about something called polyphonic strumming. I had never heard of it before, and actually the name they use for it sounds a little bit too grandiose to be accurate in my view. I kind of doubt that some people are strumming counterpoint on the guitar, though I'll accept that playing multiple parts can be considered polyphonic. Anyways, I'm a bit intrigued because I'm having a difficult time imagining what this would sound like. However, I can't find any specific examples of this technique and I'm wondering if it really exists and if it really deserves its own special terminology.
Does anyone know of (or can anyone provide) examples or further explanation about this obscure technique?
