/*
 * 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.
