Renowned pianist Alfred Brendel has referred to Mozart’s Piano Concerto No. 9, known as the Jeunehomme, as a “wonder of the world,†going so far as to assert that Mozart “did not surpass this piece in the later piano concertos.”
Later in the same article: How did Mozart, at age 21, find the burst of courage needed to write the No. 9, which pushes the boundaries of concerto convention and accepted harmonic complexity? Furthermore, after writing a great work, how does a composer move on to write pieces that are more mature but perhaps less ambitious?
