 Alkan 's large scale Duo ( in effect a sonata ) Op. 21 for violin and piano ( dedicated to <unk> <unk> ) and his Piano Trio Op. 30 appeared in 1841 . Apart from these , Alkan published only a few minor works between 1840 and 1844 , after which a series of virtuoso works was issued , many of which he had played at his successful recitals at Érard and elsewhere ; these included the Marche <unk> ( Op. 26 ) , the Marche <unk> ( Op. 27 ) and Le chemin de <unk> ( also published , separately , as Op. 27 ) . In 1847 appeared the Op. 31 Préludes and his first large @-@ scale unified piano work , the Grande sonate Les <unk> <unk> ( Op. 33 ) . The sonata is structurally innovative in two ways ; each movement is slower than its predecessor , and the work <unk> the practice of progressive tonality , beginning in D major and ending in G @-@ sharp minor . Dedicated to Alkan Morhange , the sonata depicts in its successive movements its ' hero ' at the ages of 20 ( optimistic ) , 30 ( " Quasi @-@ Faust " , impassioned and <unk> ) , 40 ( domesticated ) and 50 ( suffering : the movement is prefaced by a quotation from <unk> 's <unk> <unk> ) . In 1848 followed Alkan 's set of 12 études dans tous les tons <unk> Op. 35 , whose substantial pieces range in mood from the <unk> Allegro <unk> ( no . 5 ) and the intense Chant d <unk> @-@ Chant de <unk> ( Song of Love – Song of Death ) ( no . 10 ) to the descriptive and picturesque L <unk> au village <unk> ( The Fire in the Next Village ) ( no . 7 ) .
