A virtuoso violinist, conductor, composer, and a professor of mathematics and botany, Francesco Galeazzi (1758-1819) firmly believed that musical education should be clear, demonstrable, and practical. In 1791 and 1796, he published the two volumes of his Elementi teorico-practici di musica, a treatise that demonstrated both his thorough grounding in the work of earlier theorists and his own approach to musical study.
