Clara: It’s nice to meet you both at last. This is Babylon Alley. Here, we make it our business to know the streets, and provide children with the opportunity to control their own destinies.
Evie: Clara. Mister Green said we might be able to help one another?
Clara: In exchange for our services, we ask a small favour.
Jacob: Why not take a small favour, too?
Clara: There are several factories about the city that are powered almost entirely by child labor. Those children work long hours, with little pay, and most are not permitted even to leave the factory grounds. They suffer terribly. I need you to save them.
Jacob: A small favour?
Clara: In return, we offer you intelligence. Something YOU clearly need.
Jacob: Now hold on a minute-
Clara: I’m late for an appointment. What of these terms?
Video game music (from a game you know and play often) makes the best gentle alarm clock music because it makes you want to pay attention to your surroundings, but it’s already associated in your brain with pleasant and totally voluntary actions, so instead of an urgent ‘you have to get up and do awful shit THE DAY IS HERE PUT YOUR PANTS ON ASSHOLE’ alarm (which some people need, I know) it’s just like ‘oh, what’s that, is there a puzzle that needs solving, did I just find a treasure chest, I better sit up and look around’ vibe that leads really nicely into waking up.
Like, it’s not a sound that interrupts sleep so much as it is a sound associated with wanting to do stuff, and I find that really conducive to waking up without also wanting to die. It helps if you give yourself little rewards for getting up in the morning, too, like if you put aside stuff you want to do or look at and go ‘I will do this in the morning’. Then you have a quest, a reward, and a musical score all telling you that you gotta get up because interesting doings are afoot.
Reverse this and you get Terrible idea: setting your alarm to boss music. You will wake up instantly terrified and ready to either fight or run.
this is the exact reason why I use the Nirnroot sound effect as my alarm sound, because anyone who has played Oblivion knows as well as I do that the Nirnroot quest line has you like
every time you hear that sound for the rest of your damn life
Any Bloodborne boss music. I will never not wake up when I think I’m about to lose all my damn blood echoes.
