"His early acquaintance with the great school of Sebastian Bach, as well as his perspicacity, which enabled him to discover at an early stage the depth and incalculable richness in the works of this great master, unfathomable to so many others, and which had endeared him to this school, an institution which also demanded high precision and refinement in it's practice, something far more difficult to achieve than the glittering lustre of more recently founded schools, as well as for the harmonic part of the art, which it's master fathomed and exhausted as no one before him had ever done, all the more passionately and exclusively, since nature seemed to have denied him the delicate feeling for melodic beauty." - AMZ III, December 1800, p. 506
