The Magical Harp attacking Target Dummies. Note how the projectiles bounce, and how the distance of the cursor affects their speed.

The Magical Harp is a Hardmode magic weapon that autofires ricocheting, piercing projectiles that graphically resemble musical notes. Each projectile lasts for about four seconds before dissipating and will both ricochet and pierce enemies an unlimited number of times until this time limit is reached. Notes produce a reasonable amount of light and are not affected by gravity.

The speed of each note can be controlled by clicking closer or further from the character: Closer clicks fire slower-moving notes, and further clicks fire faster notes. The speed at which each note travels does not affect their lifespan; all last about four seconds.

The sound played upon firing resembles a plucked string, with its pitch correlating to the firing speed: Slower firings playing lower-pitched sounds, and faster firings playing higher-pitched sounds.

Its best modifier is Mythical.

Its best modifier is Demonic or Deadly for damage output, or Mystic for mana conservation because it cannot get modifiers that affect knockback.

  • Even at top firing speed, notes are still relatively slow in comparison with other projectiles.
  • Notes from the Magical Harp receive the Frost armor's set bonus.
  • The size of the game window appears to change how far the mouse/click needs to be for certain projectile speeds. Smaller screens do not have to move the cursor as far to shoot a faster/higher-pitched note.
  • The Magical Harp has a 5% damage penalty for every enemy hit.


  • Low, slow notes can hit large enemies multiple times, while fast, high notes are more likely to hit moving targets.
  • The harp's infinite piercing projectiles are exceptionally effective for killing worm-type enemies, especially The Destroyer.
  • Due to the slow speed and bouncing capabilities of the projectiles, the harp is useful for fights in small spaces, e.g. against Golem.


  • The harp's sprite is always shown while held, unlike most weapons that only show while firing.
  • The harp can be considered a direct upgrade from the Water Bolt; its projectiles have more damage and can bounce and pierce more. However the projectiles will only last 4 seconds and do not have any knockback / barely have knockback, removing the Water Bolt's useful ability of keeping enemies away.
  • Despite playing musical tones when fired, lowering the "Music" option from the audio will not make the Magical Harp go quiet.
  • The harp's notes fired appear to be quarter notes, eighth notes, and paired eighth notes, though these notes only differ visually and do not have different stats. These notes are also backward when fired, only being turned around to the correct facing after bouncing off a surface.
  • Water slows down the notes' speed even though in the real world, sound travels faster in water.


  • Desktop 1.4.1:

    • Now has knockback (knockback increased from 0 to 0.25).
    • Mana cost increased from 4 to 5.
    • For each additional target a note projectile hits, the damage is now decreased by 5%.
