About these quartets, which were written in their time for lovers and which today are a challenge even for the best musicians, one could put the words with which Mozart summed up the essence of his concerts in his letter of 28 December 1782: "They are very brilliant, pleasant in the ears, of course, without falling into emptiness, here and there even connoisseurs can receive satisfaction alone, but in such a way that those who do not know must be satisfied with them, without knowing why.'' In short: the most beautiful chamber music "for connoisseurs and lovers", played by the wonderful musicians Karel Valter (transverse flute), Pablo Valetti (violin), Peter Biely (viola) and Petr Skalka (cello).
