Harp

The Harp is a Hardmode crafting material, used only to craft the Magical Harp. While the Harp can be used itself, it has no functional use, and only makes sounds. It is sold by the Wizard.

When used, the Harp generates harp sounds. The sound's pitch is determined by the distance between your character and the point clicked. The pitch of the harp changes by a semitone for every block the cursor is from the player. It is possible to build a piano out of blocks, and play a song by clicking the different blocks.
