Quadri, Domenico



Born at Vicenza, Italy. Studied under Marchesi and Pilotti. Aside from teaching he devoted his time to theoretical research. In 1830 he published two parts of a work, La Ragione armonica, which advocated the system of building up chords by thirds. The next year he opened a school in Naples for teaching harmony. In 1832 he published another work on the   same order, Lezioni d'armonia. His innovation was not looked upon favorably by other musicians, and such was their opposition that he was forced to submit. This ruined his life, and he died in poverty in Milan.
