James Huneker,
Overtones, a book of temperaments
(1904)
“ The piano sonatas, written for money, written with ease, were also written with both eyes on the fair amateur of the period. She admired Mozart more than Haydn; his music was melodious, his decorative patterns prettier. So Mozart raged in the hearts of the ladies, and slender fingers troubled the chaste outlines of his sonatas. His eighteenth sonata, preceded by a fantasia in the same key—C minor—alone impeded the flight of these butterflies. In it were mutterings of the music that awed and thrilled in Don Giovanni, and it was a precursor of Beethoven and his mighty thunderings. ”
