At the beginning I would like to point out that I know how those scales works separately, but whenever i try to find some information/lessons/tutorial etc. about how to use them together i simply fail.
What's the problem?
For example, let's say that i'm writing a piece in A minor and i want to end some part on V-I cadence,
I raise up G to G# in dominant chord to resolve on tonic, at this point everything seems to be ok (harmonically), but what to do, specially which notes to use when i want to add melody on top of that? Seems like I can't use notes from melodic scale when i'm going down because it will make a dissonance.
How about 6th chord (right now i can't use F# and G# while going up)
It goes like that with every chord other than tonic.
So, can you provide me a good example to analyze (simply one) or describe me how to use them together?
