Library, as well as on the Discover Zelenka website. 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 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). References Sources .
