I've been learning the blues. What I love about this genre, is the element of call and response. Once one learns the scales, they can have their own dialogue.
Blues is soulful. It is eclectic and free, a precursor to Jazz. When it comes right down to it, sometimes I can't find it in myself to engage with people. I find myself too emotionally fragile to engage in the practice of call and response. That being said, I still need an outlet. Though I am not great (yet), blues allows me to cope under tremendous stress and sadness. Whether it's listening to "Little Wing" or practicing the A minor penatonic scale as fast as I can.
Gadamer once proposed that language, or the art of conversation, is nothing more than a volley of ideas and an expressed need to reach a conclusion. Language is a volley, a game.
When I try to emulate a call and response on my guitar, I have the power to create my own game of dialogue. I feel completely at ease, and can experience interaction in a whole new way.
