During his travels, Mozart often needed new pieces. In Mannheim, for example, he composed the Sonata in C major for the thirteen-year-old Rosa Cannabich, and later, in Linz, the Sonata in B flat, presumably as a concert piece for himself. These two brilliant sonatas are played here by J�r�me Hanta� on an original fortepiano of the late eighteenth century, similar to those by Stein that Mozart loved so much, and accompanied by the three wonderful rondos for piano of 1786/87. "Clarity, tranquillity, grace: the hallmark of the works of art of Antiquity is also that of the Mozartian school", wrote Schumann.
