Universe of Swords/Grand Piano

The Grand Piano is a post-Plantera projectile 'sword' with autoswing. It fires Flaming Arrows, Frostburn Arrows, Cursed Arrows, Holy Arrows, bones, shadowbeams, lost souls, fireballs, life-stealing knives, pumpkins and bubbles. It also inflicts Ichor on projectile hit. The sound it plays when swung appears to the sound of what happens when a piano is dropped off a 20 story building.

The Grand Piano becomes available after defeating Golem and the Martian Madness event.
