We can play the Sliding Standard Riff in one other position, connecting the 4th, 5th and 1st Blues Positions.
By now, you can connect all the Blues Positions through the Sliding Standard Riff.
We’ve made the connections between these positions by playing this riff on the I chord.
But the IV and the V chord also have Sliding Riffs.
These riffs are as good to glue the Blues Positions together.
Just move with the chords.
