As a conductor of the Prague Symphony Orchestra, he made several innovations. He enlarged its repertoire with the music of 20th Century and larger vocal symphonic works (including those of Rejcha, Mozart, Cherubini, Dvořák, Foerster, Martinů, Orff, Kabeláč, and Fišer). From 1938, he performed abroad. He was invited later to the many important European and overseas music centres. He primarily devoted himself to the concert music, but he also studied operas. He received many awards for his creations.
