Since every Maj7 scale has 7 modes within it, ...then obviously all 7 relative modes must also be contained in any mode's box!  SEE CHART TO THE LEFT HERE.  This Ionian example could be any mode box and all the other modes would still be there ...but with different root notes depending upon where on the neck the modes box is.

Notice that the root note position for each mode is located in the same place in each and every box!  The Ionian root note of ANY modes box is ALWAYS on the 4th string of a box's downscale fret.  The Dorian root note is ALWAYS on the 4th string of a box's upscale fret.  The
Mixolydian root note
is ALWAYS on the 2nd and 6th strings of a box's upscale fret.  All we're doing is choosing the box position for the mode we desire for the root note we desire, relative to the root's 6th chord.

Also notice that a given root note for a mode ( C Ionian in this chart example ) is always in the same place on the neck, therefore every root note for every mode also stays in the same place on the neck.  7 modes for each of 12 possible root notes is 84 mode positions;  WAY TOO MANY TO MEMORIZE;  So we use the easy
navigation template
of this course to mentally move up and down the neck relative to any root note 6th chord we desire (call it the 'Homebase' chord), to easily find all the remaing modes of THAT root note.

Notice in the above chart that the mode boxes move toward the nut in the same step sequences of the Major 7 / Ionian scale, ...which is what we would expect of modal structure, ...since the whole idea behind modes is "simply" transposing the root note to each step in the parent Maj7 scale.

Notice that the Ionian root note of each mode box is always on
the fourth string and always on a box's down-scale fret.

------- oOo -------

Likewise each root note of each mode is always similarly located in a common place in a mode box.

The box transposes up and down the neck with this modal math always intact;  With the modes in any box relative to the Ionian of where the box is mentally thought to be on the fretboard.
