Johann Nepomuk David was an Austrian composer and teacher, born in 1895, whose career began in the early 20th century and was centred on the classical tradition through roles as a church musician and conservatoire professor. His music emphasised contrapuntal technique and formal clarity, producing symphonies, concertos, chamber and choral works that combined late-Romantic harmonic language with neoclassical and neo-Baroque contrapuntal textures, contributing to Austria's mid-20th-century compositional landscape.
