Hello, All,

Again, my ignorant question #2 for the night!!

I'm working on one of the tutorials, a novice intro to 12-bar blues in E. In the third lesson, he introduces the structure of the 12-bar sequence:

|E-------|E-------|E-------|E-------|

1 2 3 4 - 1 2 3 4 - 1 2 3 4 - 1 2 3 4

|A-------|A-------|E-------|E-------|

1 2 3 4 - 1 2 3 4 - 1 2 3 4 - 1 2 3 4

|B7------|B7------|E-------|B7------|

1 2 3 4 - 1 2 3 4 - 1 2 3 4 - 1 2 3 4

My question is, I thought the 12-bar sequence went: I, I, I, I, IV, IV, I, I, V, IV, I, V, which would require an A in the 10th measure above, rather than a B7. Am I remembering the sequence wrong, or is there more than 1 way to play a 12-bar blues. Chris is my favorite instructor on here, and I'm working on a couple of his lessons. I'm just wondering if I'm missing something.

Thanks for any help or clarification you can offer!!

Peace,
Tom
