* This file contains the different functions designed to manipulate the
* musical instruments and their various effects.
*
* Actually the list of instruments / effects is :
*
* (wooden) flute may calm snakes if player has enough dexterity
* magic flute may put monsters to sleep: area of effect depends
* on player level.
* (tooled) horn Will awaken monsters: area of effect depends on player
* level. May also scare monsters.
* fire horn Acts like a wand of fire.
* frost horn Acts like a wand of cold.
* bugle Will awaken soldiers (if any): area of effect depends
* on player level.
* (wooden) harp May calm nymph if player has enough dexterity.
* magic harp Charm monsters: area of effect depends on player
* level.
* (leather) drum Will awaken monsters like the horn.
* drum of earthquake Will initiate an earthquake whose intensity depends
* on player level. That is, it creates random pits
* called here chasms.
