Hey mods! Since the world is underwater, I was just wondering how music/sound works. Is it telepathic or does it function like normal and they presumably have ears and vocal chords equipped for function under water? And on that note, I assume wind based instruments don't exist but that there are other kinds of instruments in their place? How intuitive would the instruments be for someone used to land wind instruments?

Also is...would...whistling...work? LOL I assume not but thought I'd ask. Thanks guys!!!
