A further edition in our highly regarded Beethoven revisions bears witness to our fruitful collaboration with the renowned artist Murray Perahia. This time the established editorial team Gertsch/Perahia has devoted itself to a truly monumental work: Beethoven's famous ''Waldstein Sonata'' was composed in close proximity to the ''Eroica'' and the first sketches for ''Fidelio''. The boldness of the first movement already surpasses anything that had been ventured up to that point. Beethoven dedicated it to his friend and patron Count Waldstein. As always, Murray Perahia not only provides valuable fingering suggestions but also shares his personal thoughts on this work in a short essay.
