The Galin-Paris-Chevé method is a music-reading method developed by Nanine Paris (1800-1868), her brother Aimé Paris (1798-1866), her husband Émile Chevé (1804-1864) and Pierre Galin (1786-1821), one of the method's founders, whose idea dates back to Jean-Jacques Rousseau.Although this method is largely unknown to French and other French-speaking musicians today, it is used in China under the name Jianpu ("simplified system")
