The first type of shifting is something we are all familiar with: shifting up (towards the body of the guitar) or down (towards the headstock) the neck. The second type of shifting, however, is one we all do every single time we pick up the guitar, but rarely think much about: shifting between an angled and straight left hand position. Both of these shifts are important and useful. So if we all do this all the time, why bother pointing it out?
