Mozart recorded the completion of the Rondo in his personal thematic catalog on 11 March 1787; he was age 31 at the time and had only recently returned from a triumphant journey to Prague, where he witnessed great success for a new production of his 1786 opera The Marriage of Figaro, for his Symphony No. 38, and for his own solo piano performances. notes some other major works of this stage in Mozart’s life: the Rondo shortly preceded the beginning of work on Don Giovanni; and instrumental pieces from 1787 include the Third and Fourth String Quintets as well as the string serenade Eine kleine Nachtmusik.
