   The composer Rudolf Růžička (born in 1941) studied composition 
at the Janáček Academy of Performing Arts in Brno.  Later he went 
on with his studies taking  a two-year course  of electroacoustic 
music in Prague.  Since 1969 he has been teaching  at the Janáček 
Academy where he lectures on composition  of serious contemporary 
music using computers  in the courses for graduate students.  The 
Janáček Academy in Brno is the only institution in Czechoslovakia 
where such course exists. 
   Mr. Růžička has written more than thirty compositions with the 
help of computer.  His first computer composition  is "Electronia 
B"  from  1965.    Other  important  instrumental,    vocal   and 
electroacoustic computer compositions  are:  Cosmic Symphony  for 
large orchestra, Cantata ai ai a,  Concerto - Symphony for violin 
and orchestra, Discordia, Malefica, Arcanum. 
  R.Ružička won first prizes at the international competitions of 
electroacoustic music: "MUSICA NOVA" 1970 (composition "Gurges"), 
competition Marcel Josse 1984  in Paris ("Tibia I.")  and further 
prices, and honourable mentions. He was named a member of jury of 
the  "International Computer Music Competition  NEWCOMP 1987"  in 
Boston. 
   The only book in Czech  which deals exclusively  with computer 
composition  and  analysis is  "The Use  of Computers in Creating 
Works of Art with Special Regard to Music  and Contemporary Music 
Composition" by R. Růžička (1980).
