Here is the sixth of a series of technique exercises I've dedicated to the
guitar. This is a combined warm-up exercise for both hands, but I would
suggest starting off with the R hand first (see below exer. 3 and 4).
Nervertheless I sometimes might start my daily warm up with the L hand.
In this case I would work on exer. 1 and 2 making sure my thumb is always
opposite finger 2, and moving my fingers and not my hand.
Exer. 5-8 are variations for the R hand that may inspire you to find
different formulas for different musical/technical needs.
After combining both hands, I would recommend varying the tempo,
dynamics as well as the position you practice the octaves in with the help
of a capo.
