Throughout his life, Wolfgang Amadeus Mozart repeatedly devoted himself to the genre of the accompanied piano sonata. He wrote the earliest works at the age of eight, to perform them either with his sister on the harpsichord and himself on the violin or with his father, the famous violin teacher, and sitting at the harpsichord himself. Leopold Mozart himself assured his son in a letter that he would count him among the best violin players in Europe - the composer himself preferred to see himself as a piano virtuoso and (of course) above all as a 'compositeur' who had a lot to say. The works recorded here also move within this area of tension. If the violin still plays a clearly subordinate role in the youth sonatas to the brilliant harpsichord part, which also leads in the cantabile slow movements, this distribution of roles changes over the time in favor of the violin. In the 'middle' phase of Mannheim, the renunciation of the violin would mean a painful loss, and in the later Vienna sonatas there is finally a true partnership between the two instruments with equal rights. The joyful virtuoso part is still reserved for the piano.
