This volume brings together Mozart's youthful attempts at this later so central genre of the string quartet: the astonishing "Lodi Quartet" K. 80 by the only fourteen-year-old composer, the three "Quartet-Divertimenti" K. 136-138 which are also readily played by chamber orchestras, and Mozart's first true string-quartet cycle K. 155-160 which was composed during his third (north-)Italian journey in 1772/73. Mozart's cleanly written scores of all the compositions have been preserved so that the edition stands on a secure foundation. In his informative commentary, Wolf-Dieter Seiffert, the experienced Mozart editor at G. Henle Publishers, devotes a separate, comprehensive explanatory section to the well-known articulation problem "dot or wedge." The Armida Quartet provided artistic input for this edition. - the publisher
