Modes of the Major Scale
Explore Ionian through Locrian across every key on the fretboard.
Which Ionian shape is this?
C Ionian is the parent scale itself: the plain C major scale, starting from degree 1.
There are really no separate mode shapes. Every mode is an Ionian scale of another key, played from a different degree - so find the parent key, play the shape you already know, and treat the mode's root as home.
