guitarlessons answers:

Thats because every major scale has different notes. A scale is a row of notes centered around a tonic.
Try to play a static chord, such as a C major. Then play the different modes starting on the tonic and ending on the tonic. A lot of guitarists have a tendancy to play the scale on all six strings and stopping on the last note of the shape. Which could be the third or the fourth of the actual scale.. Thats why they have problems hearing it.
Play these modes over one chord and put emphasis on the ‘chord tones’ (of the mode, not the chord being played;1357 etc..) Listen to the harmony, and the way the notes interact with chord.
It creates different tensions.
Some of the modal jazz players will play over one chord, and use the modes or tonal centre to create a sort of progression or a certain sound they are trying to achieve.

It also gives us more freedom in choosing which scales to play, instead of playing aeolian (natural minor) scale over a minor chord. We can also choose one of the other ‘minor modes’ over the same chord. A dorian certainly has a different sound than Aeolean or phrygian…
