I'm currently remixing a song, I have the vocals, and they are inthe scale of Gminor, question is how can i build melodies with/around Gminor, like do i have to stick with the Gminor scale, It feels as if im limited to what keys i can use if thats the case, but i know thats not true, I just dont know how to work with it, IS this the part where I should learn music theory?
