So I get an email with a link to a Doug Seven video about jazzin' up your playing. I like the guy and he's a hot country player that's for sure. So as he's describing what the video lesson will contain he says he'll be looking at common jazz stuff like "the sixteen, the twenty-five". Wait...what? I rewind the vid. Yep, there it is again "the sixteen, the twenty-five". Then in a flash it dawns on me what he's talking about.. I-VI-II-V or 1-6-2-5 "the sixteen, the twenty-five". Too funny. Now that's really using some verbal 'shorthand'. I've never heard anyone call it that before.
