Occupational diseases suffered by musicians constitute an area that is still unexplored, almost taboo. Many musicians have had to give up their instruments and go into conducting because they could not play any more. Others have simply retired.
Musicians have problems of sight and hearing, and other symptoms connected with the senses. There are also the back problems suffered by conductors who have to stand for hours on end. There are various nervous tics, the most common being stereotyped repetition of a particular movement. A tic that affects conductors, for example, causes them to turn the pages of the score constantly, even though they are not following it at all. There are violinists' tics and pianists' tics caused by incorrect posture. One pianist was hit by writer's cramp, paralyzing several fingers. It happens when the brain suddenly rejects the constant repetition. He was treated by a psychoanalyst and made a perfect recovery. Acute tendonitis in the shoulder which supports the instrument is a complaint dubbed "violinist's cancer". A type of obsessive phobia forces musicians to play the score in front of them because they are afraid of forgetting the notes. Stage fright is an extremely common syndrome that affects soloists at the moment they go on stage. An extreme case of neurotic disorder was the late Vladimir Horowitz, who did not play piano for years, trapped in the nightmare that his fingers might turn to glass and break if they came into contact with the keyboard.
Musicians are difficult patients, hypersensitive and delicate. Only those well versed in music can understand their disorders and weaknesses, their neuroses and the things they are touchy about. Just as a doctor treating silicosis must know all the problems involved in mining, a doctor treating musicians must know all the problems connected with music.
The Encyclopedia of World Problems and Human Potential is a collaboration between UIA and Mankind 2000, started in 1972. It is the result of an ambitious effort to collect and present information on the problems with which humanity is confronted, as well as the challenges such problems pose to concept formation, values and development strategies. Problems included are those identified in international periodicals but especially in the documents of some 60,000 international non-profit organizations, profiled in the Yearbook of International Organizations.
The Encyclopedia includes problems which such groups choose to perceive and act upon, whether or not their existence is denied by others claiming greater expertise. Indeed such claims and counter-claims figure in many of the problem descriptions in order to reflect the often paralyzing dynamics of international debate. In the light of the interdependence demonstrated among world problems in every sector, emphasis is placed on the need for approaches which are sufficiently complex to encompass the factions, conflicts and rival worldviews that undermine collective initiative towards a promising future.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
