12 bar

Today I'll start a series to help you understand, and eventually use, the common opening types found in blues that are safe to call in a sit-in (you sitting in with an established blues band) or jam session (mixture of skill and experience level of musicians) situation.

In Hob's latest lesson he plays the entire tongue block study song Temperature (focus on slaps) for me and I critique. I teach hob the bending technique of the dip and how to breathe through his nose as a pressure relief valve while playing the harmonica (as well as learning how to close the nose on inhale notes so that he doesn't fill up with air).

In the second line, the IV Chord lasts for two bars and then the I Chord for two bars. If you hear two bars and then a chord change, then you're somewhere between bars 5 and 9. continue reading...
