This is something I've given maybe too much thought about, but, since I like thinking about every aspect of my characters, I ended up thinking about almost every character's relationship with music. In the end.... most of them ended up playing an instrument or two x'D
I'd love to chat a bit about the topic with you guys :D. Do your characters play any instruments? Do you have any drawings of them doing so? Is it relevant to the story at all or is that a piece of trivia? (Don't feel like you have to answer these questions lmao, just chat about whatever you feel like as long as it fits the thread topic :3c)
About my boys:
Arckan: Owns a Spanish guitar and loves plaing it (his dad used to play one and he really really wanted to learn and play with him someday). Music can always bring a smile to people's faces<3 that's also a reason why he enjoys playing so much. Right now in the story, if he had access to his guitar, it'd be something like this tho hahahahah

Ginger: Her uncle taught her how to play the piano since she needed some medium to... Channel that stress and anger out in a healthy way x'D. She's gotten pretty good at it c: I always imagine her playing like this https://www.youtube.com/watch?v=CDFk4LxwvTY (I love this cover aaaaaaaaa). She's learning how to play the drums now in her free time.
1A/Alphonse/Ginger's uncle: He took interest in piano during his teen years (I really want to make an extra mini comic about this so I'll keep that story for myself for now), was taught how to play it and enjoyed it but can't do so now because he lacks time to invest in any hobbies atm. He's got lots of job to do 
1B/Benjamin: He doesn't have the patience nor interest to learn an instrument, but he loooves music (especially country). He loves singing along but... He hasn't got a singing voice. At all. He has fun tho so it's all good.
Sokar: They've been around for milenia, so they know quite a few old instruments. Shia (the human they're tied to) doesn't have much interest in learning music, but knows pretty much a bit of everything thanks to Sokar. I like to imagine them both making a Hurdy Gurdy themselves and then playing it under the stars <3
The bad bois' boss: He took piano classes and got thaught how to play an organ. It fits him too much hahahaha.
Can't talk about the rest of the characters because they haven't appeared yet </3.
Music doesn't have any important role in my comic but I still love thinking about them playing something in their free time, what it means to them, the situations that could happen between the characters due to music or just... Them enjoying it a lot c:
Enough on my ramble tho, can't wait to hear you guys' take on the topic
