The Oboe Quartet in F major, K. 370/368b, was written by Wolfgang Amadeus Mozart in early 1781. The quartet is scored for oboe, violin, viola and violone basso or cello. In 1780, Mozart was invited to Munich to visit Elector Karl Theodor, who had commissioned the opera Idomeneo for a carnival celebration. While in Munich, Mozart renewed an acquaintance with Friedrich Ramm, a virtuoso oboist in the Munich orchestra. It was for Ramm that Mozart composed the quartet in order to show off his virtuosity and the improvements that had been made to the oboe at that time. One way that this piece showed off the instrument was the use of the "high F" above the staff, a note rarely played in any repertoire previously written for the oboe.
