Quartet, No. 13, in F. The first movement, Allegro con brio, F major, four-four time, opens with a theme of a declamatory type, and the expression is dramatic. The second subject in C, is in the style of the Italian _aria_, concluding with the lively _Cabaletta_ strain. A short _Coda_ ends the first part. In the working out section there is an important episodial theme for the violoncello, and in the recapitulation the second subject, now in F, is allotted to the viola, the violin taking up the _Cabaletta_. Both parts are marked for repetition. Minuetto, Allegretto, F major, three-four measure. The violin has the theme of the first strain of eight bars repeated; the violoncello responds with the subject of the next strain of twenty-five bars, one phrase lengthened to five bars. The Trio in B flat has a tripping theme for the viola, legato and staccato bowing in the same "figure." Later the phrases are broken into dialogue for violin and viola. In the Minuet the guitar has a "second" to the violin melody. Larghetto tenuto, con anima, D flat major, six-eight rhythm, a broad, cantabile theme for the violin, with spare embellishment. The movement must be slow, for there are arpeggios of eight notes to the quaver beat in the guitar part. Finale, Prestissimo, F major, two-two measure. The theme for the violin resembles very much some of those merry "tributary" motives found in Mozart's symphonies towards the close of the first part of a movement--the "Jupiter," first movement for instance. The second subject affords contrast. The whole is most spirited and light-hearted. Paganini must have been in a happy mood when he wrote this quartet.
