Introduction
This tutorial aims to show a lot of blues style techniques that
are possible while holding down an open A major chord.
It is important to use the shape shown so if this way of playing an A chord
is new to you it's worth spending some time just on the chord before launching
into the lessons.
The chord itself is very easy - it's more the right hand selective strumming
that may require a bit of practice to avoid hitting the top and bottom strings.
