This work is big! Can a fortepiano of the day do it justice? A relatively modern instrument struggles at points with this although a modern grand would probably be more convincing of the score with its dynamic range and dense harmony. This sonata looks forward to the later works Beethoven produced – I’d place this alongside Op. 22, the Waldstein and the Appassionata in ‘Grandness’. It is also second only to the Hammerklavier in terms of performance duration. I took a decidedly free approach to the first movement rhythmically particularly in the second subject and caddice material and I took my tempo of the 4th movement from a leisurely Allegretto due to the inclusion of ‘Grazioso’ in the instructions.
