I don't know if it's really a hard part, but after getting the arrangement down, and stating to actually mix the thing, polishing all the wrinkles so it starts to actually sound good instead of just me thinking it's fine, that seems to take hours and hours and hours for me. I can't believe people whip up tracks that are ready to go in just a couple of hours.
I used to have no sense of structure, flow, transitions etc. I'm not sure I do now, but at least I realize you can't just slap two parts together and think it's fine.. or completely change into different style and practically a different song if you run out of ideas/skill how to progress what you have. Well, it CAN work, but I apparently used to think it would always work. Man, my old pieces are so bad.
I was reminded of that by what Nutritious said, and I'm currently working on that exactly on my Gunstar Heroes track.. this is a Gunstar Heroes project mixers support group gathering.. turning the ideas into an actual structure. It's kind of hard, but mostly it's just lots of work. I feel that's different from actually hard.
What's the hardest for me is that I'm trying to play lots of guitar on the track. Any live recoding I try to do, I have such a sense of ineptitude that it's really clouding my judgement. That's hard and I should just get over it, just work it, but I need to get past of everything sounding shit to me. Most of it does, but I'm sure there's that one take that's actually good, or at least good enough, and I don't want to miss it just because I get depressed.
And the actual hard part is not having the time I wanted to make music.
