Mozart Duos for Violin and Viola K 423 and K 424

After moving to Vienna in 1781, Mozart returned only once to his hometown of Salzburg, and that was from the end of July to the end of October 1783 in the company of his young wife Constaze. Just as we know little for certain about the events of those months, Mozart also seems to have composed equally little there. Just these two exquisite duos for violin and viola come from this period, and even they were apparently written as a friendly favor for Salzburg composer Michael Haydn (younger brother of Joseph Haydn), who for reasons of acute ill health was unable to complete a commissioned composition. Henle's Urtext edition is based on the carefully notated autograph manuscripts; the first edition appeared only in 1792, shortly after Mozart's death, making its value as a source debatable. In addition to a complete score of this wonderfully intimate chamber music, foldout instrumental are included, facilitating comfortable performance.
