1 Gr. word taken into Lat. and sometimes used by composers instead of ‘symphony’. Thus R. Strauss's Symphonia Domestica is correct title given by composer, not Sinfonia Domestica (It.).
2 Name given in medieval period to hurdy‐gurdy, first str. instr. to which kbd. principle was applied. Perhaps so called because it was used in polyphonic mus., a master of polyphony being then sometimes called a symphoneta (Gr.).
