All of the study scores minutely follow the musical text contained in the uncontested reference edition by the Joseph Haydn Institute in Cologne, whose scholarly critical Haydn Complete Edition is also published by Henle Publishers. Each quartet opus reflects the latest in scholarly research and is introduced by an informative preface. The musical text fulfils the highest aesthetic demands. A welcome present for every chamber music fan and the basis for every serious quartet player who wishes to play or study these works.
