I have started a hip hop song and usually I stick to either a major or minor key for the song. I have started with a melody, (not chords) just keys. Goes G# C# C# C# D# E repeats and then i do exactly the same but This time changing the root... to A instead so it goes A C# C# C# D# E... Now to me it sounds good and not off in anyway but the A key isn't in the scale of G# MINOR NEITHER is it in the key of G# MAJOR.... So can someone tell me if this is acceptable to use the A key and also am I still in G# MINOR as all other keys used are in that scale, just the A key isn't... I UNDERSTAND scales etc but with this track I have just kind of improvised...
