KSE aren't very hardcore, but they still go on the hardcore forum but this would probably go on the song writing forum.

Anyways... I wouldn't expect most metal, hardcore, punk, alternative, noise rock, ect bands write out sheet music of what they're going to play, but they might. But personally, I have a grindcore project and I write everything out as tabs before I get around to recording it.

bedeckt sie die Welt
mit undurchdringlicher Dunkelheit.
Kälte steigt vom boden auf
und verpestet die Luft
hat das Leben neue
