This collection of ten compositions for string quartet by Mozart includes six pieces dedicated to Joseph Haydn and three pieces composed for the king of Prussia. The King of Prussia for whom Mozart composed some of these quartets for was by all accounts a Cellist of no mean ability; especially if one may judge by these works whose Cello parts are elaborate and demanding often soaring into the upper ranges leaving the viola to take up its momentarily abandoned role as bass instrument! Works include String Quartet No. 14 in G major K387 'Spring' String Quartet No. 15 in D minor K421 String Quartet No. 16 in E flat K428 String Quartet No. 17 inB flat major K458 'The Hunt' String Quartet No. 18 in A Major K464 'Drum' String Quartet No. 19 in C major K465 'Dissonance' String Quartet No. 20 in D major K499 'Hoffmeister' String Quartet No. 21 in D major K575 'Prussian No. 1' String Quartet No. 22 in B flat major K589 'Prussian No. 2' and String Quartet No. 23 in F Major K590 'Prussian No. 3'

Appony Quartets-Joseph Haydn composed the string quartets known as Op.71/74 also called the 'Apponyi' Quartets in 1793. The composer dated the autograph scores accordingly although the year that appears on those of the B flat major and D majorquartets shows signs of having been corrected. These two works might already have been finished in 1792. However it is certain that Op.71/74 were composed in Vienna during the period between Haydn's two journeys to England andintended as a series of six quartets.The decision to divide the quartets into two sets of three was taken by the publishers. The three Quartets Op.71 were first published in 1795 by Corri Dussek & Co. then in a slightlyrevised reprint by the Viennese publishing house of Artaria & Co.
