Beethoven's independent sets of variations for the piano are here published in three Urtext volumes, arranged in chronological order. This third volume contains works dating from 1803-1823. All sets of variations which are authentic, complete, and written for the piano are included. The musical text presented here stands as close as possible to what Beethoven wrote down, and contains only additions which were held to be desirable and necessary by the musical and publishing practice of the time. Editorial additions are kept to a minimum and appear in square brackets or are explained in the notes. No suggestions have been made regarding the manner of the performance, the execution of ornaments, or the pedaling and fingering, although Beethoven's original pedaling and fingering are included unchanged.
