say im playing a 'riff' in A minor, then i play a C# minor followed by an A major, what are the relationship between A and C#
since A minor hasnt got a C# in it, why does it sound right?
what im trying to say is why does going from A minor to C# major work when they're in a different key.
To put it simply, you are momentarily changing the key of the song.
Personally I just played the progression you laid out, and I
don't think it sounds good. (At least in the voicings I played it in - perhaps you play it a different way). But some people dig that kind of dissonant, doesn't belong there, type of sound in a song.
