German Classical-period composers

Johann Gottfried Müthel (January 17, 1728 – July 14, 1788) was a German composer and noted keyboard virtuoso. Along with C.P.E. Bach, he represented the Sturm und Drang style of composition.
As far as is known, he was the first to use the term fortepiano in a published work, in the title of his Duetto für 2 Clavier, 2 Flügel, oder 2 Fortepiano (1771), which reflects the rising popularity of the instrument at that time.

Daniel Gottlieb Steibelt (22 October 1765 – 2 October [O.S. 20 September] 1823) was a German pianist and composer. His main works were composed in Paris and in London, and he died in Saint Petersburg, Russia.
