Quartet, No. 11, in B major. For this the guitar is tuned a tone higher, the _capo tasto_ raising the E strings to F sharp, and the guitar part is written in the open key of A. The first movement, Allegro moderato, B major, four-four rhythm is free in form, with repeat of the first part. The thematic material is assigned chiefly to the violin, but in the second part there is an episode, a sort of folk-tune, given to the violoncello. Minuetto, Allegretto, B major, three-four, with Trio in G major. The melodies are fresh, and move step-wise, very much like those in the Minuet of Beethoven's first Symphony. They are in scale formation, up and down, and there is only one skip of a third in the first sixteen bars. Again the violin takes all the themes. Larghetto con passione, F sharp minor, six-eight measure, a Lament, a fine expressive theme, opening nobly, but with the elevated style not maintained throughout. The viola and violoncello parts are in keeping with the pathetic feeling of the movement, but the rhythmic figure of the guitar part detracts from its dignity. Polacca, Andantino mosso, B major, three-four measure, a well-written movement, with three clearly defined subjects, two of which are taken up by the viola and violoncello. The violin part in this quartet is brilliant, but not particularly difficult; there is no double-stopping, excepting in chords of accompaniment. Quartet, No. 12, in A minor. This number is in three movements only. The first, Allegro giusto, A minor, four-four rhythm, is quite orchestral in character, and opens with a theme of symphonic breadth. There is science displayed in the development of this movement. In the first part the second subject is in C major, and in the recapitulation in A major. The slow movement, Adagio tenuto, con precisione, C major, three-four measure, has at first a very broad and declamatory theme for the violin. The writing becomes very elaborate, and the rhythmic figuration complex, passages with four and five-stroke notes occurring. The Finale, Minuetto, Allegretto mosso, is a fully developed movement quite in sonata form, with first part repeated. The exposition has a first subject of two extended members, the second in the major mode. The second subject, in E, is well contrasted. There is a long working out section, with episodial matter, and the recapitulation is very happily led up to. The music has a lilt that is irresistible, and the writing is interesting for each instrument.
