The Viennese Tuning Collection is created to provide a completely revised and corrected edition for the modern Viennese Bass player as well as the modern Bass player who wishes to play it in solo-tuning. Both parts are provided and just a few details have been changed for the modern solo-tuning, concerning its playability. The edition preserves the original music with the minimal interference from the editor, that due to the circumstances in which the originals are, realized small corrections in articulations, dynamics and wrong notes. In an effort to make the Viennese tuning and its praxis more popular between modern Bassists, it has been adapted to modern notation (sounding one octave down as written).
    The Duet in D major for Viola and Double Bass from Johannes Matthias Sperger is presented here in an “Urtext” edition, based in the original manuscripts preserved and kindly provided by the “Landesbibliothek Mecklenburg-Vorpormmen Günther Uecker”.
