The String Quartet no. 23 in F major, K. 590, was written in July 1790 by Wolfgang Amadeus Mozart. It is the third of the Prussian Quartets. The quartet was written for and dedicated to the King of Prussia, Friedrich Wilhelm II, an amateur cellist. It is written in a similar style to the quartets of Joseph Haydn. Mozart and his friend Karl Lichnowsky met the king in Potsdam in April 1789. Mozart played before the king in Berlin on 26 May 1789. A typical performance lasts around 26 minutes.
