The 1-2-4 Combination Exercise
Slurring Stringed instrument Slurs with the first, second, and fourth fingers is critical to your legato playing.
Go slowly at first making sure each movement is smooth and as effortless as possible.
Warning! If you begin to feel any pain at all, take a break.
Expect the conditioning to take up to a month for this type of slur! 
If you rush the process you may develop improper technique or
worse, cause un-needed injury.
Within each segment there is an ornament-like slur from the
4th to the 2nd finger. These two notes will be at twice the tempo of the section.
For example, within the quarter note section, there will be
two 1/8 notes. In the 1/8 note section two 1/16th notes,
and in the 1/16th note section two 1/32 notes.

I use to play the clarinet a few years ago and I remember slurring although this is the first time I have heard of it used when playing a guitar. (I don’t get out much). When I get home today I am going to give it a try. You are truly a gifted teacher.
Slurring on wind instruments is basically the same. On guitar it’s endemic to practically all music styles. It’s not hard but at first more clumsy than anything! Let me know how I can help Tammy Jo!
Thank you Mark.
