when making a song, i can have a few isolated parts but have no idea how to put them together in a way that makes sense, how do you go about this situation?
i've almost never seen that work. if you have 2 separate parts that are not together, sticking them together usually doesn't seem to work, at least not for me. i find it's much better to just play through one of them, and then try to imagine what goes next. and don't worry about the other part that was never connected. You can do the same thing with that part. 2 songs
