Can you give me some advices how i should learn the different scales? Here is what I know: I know Major scale and Pentatonic scale, but i only know them in patterns. So i heard that the idea of pattern is bull****, and that it can limit your creativity(which might be true for me). I´m planning to learn the whole fretboard in notes, so that I can change keys easily, if I just remember the basic note of each pattern. I already know half of the notes by heart.

So but now my two questions:

1)If I know the whole fretboard in notes, is there a better way to learn scales?

2) I don´t understand for instance, what the difference between C major scale and C Ionian Mode is, or when they say I play D Dorian Mode over the whole fretboard, why don´t they say I play G mixolydian Mode or A Aeolian Mode over the whole fretboard, because that´s the same, isn´t it?
