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'

Richard Reed Parry's Quartet For Heart And Breath is an innovative and original piece based on the performers' own bodily rhythms. This sheet music is for String Quartet(Violin/Violin/Viola/Cello).Richard Reed Parry is familiar to millions as the lead singer of rock band Arcade Fire yet his foray into classical music is equally worthy of attention. Quartet For Heart AndBreath is an experiment into using the performers' heartbeats and breathing to dictate the tempo. The performers are instructed to wear stethoscopes in order to listen to their heartbeats closely while one completebreath corresponds to one bar and two heartbeats equal two crotchets.The result is a quiet and subtle piece as each instrument has to play softly so as to be able to keep in time. The piece also has a naturally occurringdynamism in that the players' heart rates constantly change as the performance goes on with each instrument falling in and out of sync sometimes culminating in a beautiful moment of all heartbeats matching each other.Interestingly this unique aspect means that no performance will ever be the same meaning to hear or play this composition will be a truly once in a lifetime experience.Quartet For Heart And Breath is asuperbly one-of-a-kind composition by Richard Reed Parry. Commissioned by the Kronos Quartet this piece makes for a wonderfully distinctive performance with fascinating implications for the connection between the musicand the body.
