7.     * musical instruments and their various effects.
8.     *
9.     * Actually the list of instruments / effects is :
10.    *
11.    * (wooden) flute	may calm snakes if player has enough dexterity
12.    * magic flute		may put monsters to sleep:  area of effect depends
13.    *			on player level.
14.    * (tooled) horn	Will awaken monsters:  area of effect depends on player
15.    *			level.  May also scare monsters.
16.    * fire horn		Acts like a wand of fire.
17.    * frost horn		Acts like a wand of cold.
18.    * bugle		Will awaken soldiers (if any):  area of effect depends
19.    *			on player level.
20.    * (wooden) harp	May calm nymph if player has enough dexterity.
21.    * magic harp		Charm monsters:  area of effect depends on player
22.    *			level.
23.    * (leather) drum	Will awaken monsters like the horn.
24.    * drum of earthquake	Will initiate an earthquake whose intensity depends
25.    *			on player level.  That is, it creates random pits
26.    *			called here chasms.
