Among Vienna’s many composers and pianists of the time, Anton Eberl (1765–1807) was the one considered most worthy of comparison with Beethoven. His Sonata in B flat major, Op.35, his last of seven sonatas with violin, was composed around 1805 and dedicated to Maria Walburga, the Princess Bretzenheim. This was one Eberl’s last works, as he died prematurely, at the age of forty-one, in 1807. Unlike many of Eberl’s lesser contemporaries, in its duration, formal and harmonic novelty, and in the lively relationship between the violin and keyboard, his Op.35 shares much of the musical ambition and quality of Beethoven’s works in this genre.
