These neck illusions fingerboard graphics are a great way to teach players the locations of all of the notes on a guitar.  Makes learning scales easier as well.  As the player advances, they can remove the decals of the first octave of the fingerboard (up to the 12th fret) while keeping the second octave on the fingerboard to help remind them the position of the notes if they need it.  Also included with our teaching tools is a Neck illusions chord chart.
