Mozart Violin Concertos

It is likely that Wolfgang Amadeus Mozart planned the three violin concertos he composed between October 12 and December 20, 1775 as (part of) a cycle. This is indicated by both the proximity of the dates of these works and the systematic design of the keys – G major, D major and A major: in other words, covering three of the open strings of the violin. Furthermore, the last movement of all three concertos is a French “Rondeau”. Strangely enough, after writing his Concerto in A, Mozart appears to have lost all interest in the genre. The following year, he added a kind of violin concerto, consisting of an Andante, Minuet and Rondeau, to his Haffner Serenade K. 250, but that signalled the end of his interest in the violin. From that moment onwards, the piano was the instrument he preferred to use in expressing himself. This caused his father, Leopold, great displeasure, by the way: more than once, he admonished his son as follows: “Du weisst selbst nicht, wie gut Du Violin spielst…”.
Although as a rule Mozart’s letters provide an excellent insight into his life and ideas, we have no idea what caused this sudden loss of interest in the violin. Was it just a case of the adolescent rebelling against the authoritarian father? Or did Mozart associate the violin too closely with the oppressive Salzburg courtof archbishop Colloredo, who in fact dismissed Mozart summarily in the August of 1777?
