These are the 5 positions of the Major scale.  The root note is the note
that determines what the scale is called.  Such as, Gamjor, Amajor Bbmajor
etc. Some of these scales require some position shifts, i.e. where you have to
adjust your hand to get to the next note. I've notated the fingerings as to
make this a little easier.

The Major scale is based on scale degrees.  I  II  III  IV  V  VI  VII VIII
these are determined by half and whole steps.  A half step you can think of
it as going up or down one fret.  Like from B to C or D to D#.  A whole step
is like going up two frets.  B to C# or A to B.

I-II whole step
II-III whole step
III-IV half step
IV-V whole step (continue)
