Here is a summary of effects of musical instruments.

Distance below means the sum of the squares of the horizontal and vertical offsets.

Magic flute

• If confused or has no charges, behaves as a wooden flute.
• "You produce soft music."
• Monsters within a distance of 5 * explevel have to resist or fall asleep for 10d10 turns.
• Exercises dexterity.

Wooden flute

• If confused or a random number in the range 0 to dexterity + explevel - 1 is 25 or less,
  • then
    "The <flute> toots."
  • Otherwise
    "The <flute> trills."
    All snakes within a distance of 3 * explevel become peaceful.
• Exercises dexterity.

Frost/Fire horn

• If confused or has no charges, behave as a tooled horn.
• Behaves as a wand of cold/fire except that the damage will be nd6 (where n is 6 to 11) instead of 6d6.

Tooled horn

• "You produce a frightful, grave sound."
• All monsters within a distance of 30 * explevel are awakened and no longer immobile.
• Monsters within a distance of 10 * explevel have to resist or beginning to flee.
• Abuses wisdom.

Bugle

• "You extract a loud noise from the bugle."
• All soldiers and guards on the level are no longer peaceful, asleep or immobile.
• Abuses wisdom.

Magic harp

• If confused or has no charges, behaves as wooden harp.
• "The <harp> produces very attractive music."
• Monsters within a distance of floor((explevel - 1) / 3) + 1 have to resist or become tame.
• Exercises dexterity.

Wooden harp

• If confused or a random number in the range 0 to dexterity + explevel - 1 is 25 or less,
  • then
    "The <harp> twangs."
  • Otherwise
    "The <harp> produces a lilting melody."
    All nymphs within a distances of 3 * explevel are awakened and made peaceful.
• Exercises dexterity.

Drum of earthquake

• If confused or has no charges, behaves as a leather drum.
• "You produce a heavy, thunderous rolling!"
• "The entire dungeon is shaking around you!"
• Cause a force floor((explevel - 1) / 3) + 1 earthquake centred on you:
  On all points whose vertical and horizontal offsets are no more than twice the force from the epicentre:
  • monsters become hostile
  • there is a 1 in (14 - force) chance that a pit will open up on the spot (if that spot had a fountain, sink, altar, throne or was an ordinary room or corridor) or a door collapse. Other locations are unaffected (e.g., stairs remain there :)
• All monsters within a distance of DungeonRows * DungeonCols are awakened. (this will be the whole level unless you are near a corner, I think).

Leather drum

• "You beat a deafening row!"
• All monsters within a distance of 40 * explevel are awakened.
• Abuse wisdom.
