i guess i got a posture from walmart that has tons of scales and modes on them. but what really helped me was learning theory by numbers. i got all the modes in numbers from UG. like the dorian

1 2 b3 4 5 6 b7 1.

i personally wouldnt waste money on a book. its all over the interenet. the chromatic scale is

1 b2 2 b3 3 4 b5 5 b6 6 b7 7 1

and the major scale is

1 2 3 4 5 6 7 1

its confuseing at frist but if u write it down and look at it everyday one day ull understand.
everything is in the chromatics...ITS AMAZZAAZZIIINNNGGGG
