Variation, Part 3 - Hook Example (Octave)
The first step in experimenting is to move your hook up or down an octave...
I7 = 2 2" 2 turns into 6+ 5 6+ (or 9+ 9 9+ in rare cases)
IV7 = 4+ 3' 4+
V7 = 4 4+ 4 turns into 8 7+ 8, but due to the IV7 not being able to be moved up an octave negates this option
And your Bb Harmonica in 3rd Position...
I7 = 4 4+ 4 turns into 1 1+ 1 or 8 7+ 8
IV7 = 6+ 5 6+ turns into 2 2" 2 or 9+ 9 9+
V7 = 6 6+ 6 turns into 3" 2 3" or 10 9+ 10
Note that 3rd Position has more options, which is often the case. If you haven't experimented with 3rd Position, maybe it's time you do? Have a great weekend everyone.
