Critical edition for today's performers, teachers and scholars, faithful to the original notation, correcting long-standing errors found in other editions. Presents new and important research with an introduction covering editorial method commentary to the sonata (as a separate insert), including history, full assessment of the sources and detailed notes on interpretation.
