What does that positioning (short-arm/teeter-totter) look like?
Generally, a player with long limbs will place his right hand PIMA on the rear portion of the soundhole on strings “D”, “G”, “B”, and “E” to achieve a “standard tone”. If they keep their wrist fairly straight and avoid excess flexion (bending) in the wrist, a person with long forearms will have a fulcrum somewhere between the wrist and the elbow. This type of fulcrum is called “the short arm” approach.
