The opus of Stevan Stojanović Mokranjac encompasses several areas of music. In the domain of vocal music Mokranjac creates works of worldly and spiritual music, scene music for theatre purposes, children’s songs, solo songs to the verses of well-known Serbian poets and some Serbian custom folk chants. As far as instrumental music goes, there is the 5th fugue as the obligatory piece in the studies in which Mokranjac shows his fine knowledge of counterpoint, as well as pieces for the string quartet.
   Mokranjac engages in melographic work and registers folk songs from all south Slavic nations. He also writes theoretical papers on musical folklore. Mokranjac practically engaged in chamber music, being one of the members of the first Serbian string quartet.
