Johann Gottlieb Gorner (also spelled Gorny) was a German composer and conductor active during the late 18th and early 19th centuries, primarily associated with the genres of classical and sacred music. Born in 1760, Gorner's musical career was notable for his contributions to choral and orchestral works, particularly in the realm of liturgical compositions. One of his significant contributions is his "Missa in C," which showcases his skill in vocal writing and orchestration, reflecting the style of the classical period. He also composed various cantatas, symphonies, and chamber music that illustrated the transition from the Baroque to the Classical style, incorporating elements of both. Gorner had a lasting impact on the development of church music in Germany, influencing later composers in the genre. Although not as widely recognized as contemporaries like Haydn or Mozart, his works are valued for their melodic inventiveness and harmonic richness. His music is often performed in choral settings and remains a part of the repertoire in some church music contexts today. Gorner's contributions helped lay the groundwork for the evolution of German sacred music in the 19th century.
