Sr.s first video to blog

This little blues showed up a while back, and I decided to video it so I could do a first post and do a little tutorial and propose a little blues:  

first: when I say BM7 as the end chord in the riff, it should be BbM7

then, a quick note about voicing in circle of fifth patterns--a neat sound is the chromatic half- and full-step movement of one note as the chords go by, here my C# C Bb)

     chromatic half- and full- tep movement of one note in circle of fifths chord movement("Don't 
          wait too long," e.g., and this tune C# C Bb in my blues here)

then, a little theory

     In a diatonic scale (7 pitches--like G A B C D E F--) a typical chord pattern is written
          I (tonic) ii (minor second) iii (minor third) IV (fourth-sub-dominant) V (dominant) vi (6th)
          vii (diminished). . .in this blues, I'm modifying it so the tonic is minor (i) the 2nd is Major
          (II) and the 5th is "modified"--bass, D, right hand G A C E)

     In the key of Bb, Gm is the so-called "relative minor," which is the name of the
          key this blues is in
      the 4 chords in this blues are typical chords in the diatonic ("a scale composed of seven distinct
            pitch classes")--G A B C D E F, shown in this blues (A7 D7 Gm7. . .chorus Gm7 Dm7
            modified)


Now, to stop your eyes from spinning, the actual video:
