hello, everyone..thx u for replying my question..thx u so much...

u all have added me a lot of new idea n knowledge..thx u so much
JonR : ..i'm sorry, but i think u miss my point..i am not asking "what pattern to use over that progression"..but what i am asking for is : can i use any other modes/scale from unrelated keys for any chord in a progression as long as that scale/modes have the chord tones?
as example:
on that Am standard progression: Am F G
..can i use F myxolydian scale over that F chord since the F myxolydian have all of F triad chord tones? or can i use A harmonic minor over that Am chord, since the A harm.minor have all the Am triad chord tones?
if i can't, why? i notice that Chris J has given me great explanation about this..(thx u so much,CJ

)...but i really would like to read your comment too...
i'm sorry if i am the one who misinterpret your explanation..please straighten my thinking to know what you really mean in your explanation above..
thx u so much again
