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 Jerome Hantai 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.
