Koffler only contributed three texts to Kwartalnik Muzyczny (a periodical published in 1928–1933 in Warsaw). These were: two extensive reviews of German-language books by Egon Wellesz (Koffler’s teacher at the University of Vienna) and Hermann Scherchen, as well a paper on diatonic modulation (printed in a double 1931 issue entirely dedicated to music education, in the context of a reform carried out at Warsaw’s State Music Conservatoire).
