Reshape the Song

Evan died on a kitchen floor with a rock concert roaring on the other side of the wall-the stage he had always wanted and never reached. Then he wakes as Kai Ashbell, the son of a tavern family in a magic world where songs can mend stone, shape mana, and command respect. There is only one problem: this world has no guitars. No amps. No rock. No sound with teeth. In his old life, Evan could hear every mistake in a song but could never sing one right.
In his new life, Kai receives a humble craft skill called Reshape, meant for fixing warped plates, bent spoons, and tavern tools. But Kai sees something no one else does. Wood can be hollowed. Wire can be tightened. A forbidden new sound can be built by hand. His first crude guitar is ugly, unstable, and almost impossible to play. It also attracts monsters. As Kai chases the sound he could never abandon, his strange music pulls him into danger far beyond the tavern walls: suspicious mages, sacred singers, monstrous hunts, a cursed voice that should not be heard, and a world that treats "proper music" as law.
Every chord he strikes risks ridicule, blood, and something far worse than failure. But Kai knows the ache of standing outside the stage. If this world has no place for rock, he will make one. Reshape the Song is an action-packed isekai fantasy adventure about music magic, crafting progression, monster battles, found family, and one tone-deaf cook's impossible rise in a world that has never learned how to scream.
