english is not my native language so forgive my mistakes....
learning scales C major (C) and A minor (Am) I've noticed that they have the same notes on the fret board, from that i saw that they share the same scale chords. (and its so for all major and minor scales)
that raised some questions for me:
is it correct to say that Am scale is the same C scale just starting in a different note (with the formula shifted 2 steps) ?
why are we looking at them that way and not just as C scale ?
what scale is a certain chord progression like C - Am - F - G ?
when will i refer to that progression as C or as Am ? or when it will have a sad (minor) sound and when it will have a happy (major) one ?
and a lot more...
if some one can help me understand this
