The total number of Zelenka's known and attributed opus-numbered works is 249. The sacred vocal-instrumental music is at the center of his compositions and include over 20 masses, four extensive oratorios and requiems, two Magnificats and Te Deum settings, 13 litanies, many psalms, hymns, and antiphons. Zelenka also wrote a number of purely instrumental works – six trio or quartet sonatas, five capricci, one "Hipocondrie" and other concertos, overtures and symphonies. The most appreciated of Zelenka's sacred works are probably his masses, above all his "Missa Purificationis" (ZWV 16, his last mass to include brass instruments) and his final five pieces (ZWV 17–21), commonly called "High Mass" compositions, written between 1736 and 1741 and considered as Zelenka's compositional peak. The last three were also called "Missae ultimae" (Last Masses). The list below contains only the most important sacred works, that have been sufficiently explored to date. Masses and requiems   Oratorios   Litanies   Psalms and hymn settings   Other liturgical and spiritual works   Zelenka composed only a few extensive vocal-instrumental pieces on secular themes, but one of them – "Sub olea pacis et palma virtutis"--"Melodrama de St. Wenceslao" (1723) – not only represents one of the high points in baroque music, but transcends it, as with many others of Zelenka's works. It is a monumental opus with aspects of melodrama, oratory and contemporary opera, composed for the coronation of Charles VI by the Czech king and celebrating the memory of the greatest Czech saint and patron of Bohemia, prince St. Wenceslaus (Václav), one of the founders of the Czech state.
