Johann Georg Christoph Schetky (1737-1824) grew up at the court of Hessen-Darmstadt where his father was in service to the landgrave Ludwig VIII as a musician and secretary. Schetky studied composition with Samuel Endler and cello with Anton Filtz. Later, he played the cello in the Darmstadt Court Orchestra, and from 1768 he gave concerts as a freelance cellist, at first in Hamburg and from 1772 in London. In 1774 he became principal cellist of the Edinburgh Musical Society and married the daughter of the Austrian cellist Joseph Reinagle (1762-1836). The cello duets op. 7 were written for teaching purposes and first published in 1780. The duets are extremely suitable for tuition. There are rewarding exercises for both players - tailor-made for the instrument.
