She learned piano in Vilém Kurz’s class at Lwów’s GTM Conservatoire, musicology at Lemberg University (i.e. Lwów, from 1912) and for one semester at the University of Vienna (1915). In 1929 she completed her studies at the Jan Kazimierz University in Lwów, presenting a dissertation On Claude Debussy’s Harmony.
In ca 1932–37 she taught theory at the Karol Szymanowski Music Conservatoire in Lwów. In 1930–31 she was deputy president, then from 1931 – president of the ISCM Lwów Branch. She published texts in many periodicals (as a permanent reviewer for Gazeta Lwowska, among others), but only sporadically in journals edited by Koffler: an article on ‘Instrumental Music in the Seventeenth and Eighteenth Centuries’ in Orkiestra (1933) and ‘Why We Should Educate Our Children Musically?’ in Echo (1936).
A well known press debate between Koffler and Łobaczewska was published in Orkiestra(Przemyśl) and Muzyka (Warsaw) in 1936. Koffler criticised Łobaczewska’s claim that Alban Berg’s oeuvre represents leftist tendencies in music. He defended the autonomy of music and its freedom from political affiliations.
In 1940–41 Łobaczewska (like Koffler) found employment at the LGK Lviv State Conservatoire. In 1944, she settled permanently in Kraków, and in 1945 started teaching at that city’s State Higher School of Music, holding the post of its rector in 1952–55. She obtained a postdoctoral degree in 1949. In 1951 she also took up a teaching position at the Jagiellonian University’s Institute of Musicology, of which she was the head in 1954–63.
