Sarrusophone Spartiti Musicali
The sarrusophone is a family of metal instruments allegedly conceived by Pierre-Auguste Sarrus (1813–1876) and patented by Pierre-Louis Gautrot in 1856. Sarrusophones are transposing instruments that employ a key system almost identical to that of the saxophone, which led to some copyright conflicts between the makers of the two instruments. Though the sarrusophone fell out of use pretty fast, one of its goals was to serve as a replacement for oboes and bassoons in wind bands.
