视频介绍： 貝多芬 : 降B大調為單簧管、大提琴與鋼琴所作的第四號三重奏Op.11 Beethoven : Trio for clarinet, cello & piano No.4 in B flat major Op.11 Clarinet : José Franch-Ballester Cello : Ani Aznavoorian Piano : Warren Jones Description : The finale, a set of variations, is based on the theme of the trio Pria ch'io l'impegno, from Joseph Weigl's opera L'amor marinaro of 1797. Weigl (1766-1846) was a composer and conductor at the Kärntnertor Theater in Vienna. The most striking feature of the Allegro con brio first movement is the transition between the first and second themes. After a convincing modulation to the dominant, F major, what sounds like a second theme begins, but on D major. This quickly dissolves into fragments of the first theme and leads to the actual second theme, appearing first in the piano in F major. Beethoven forgoes the D major episode in the recapitulation. Beethoven sets the central Adagio in E flat major. In sonata form with a brief development, the movement's recapitulation is highly decorated. The finale is as much a vehicle for Beethoven's piano virtuosity as it is an example of his variation technique. The first variation is for piano alone and features detached runs and tremolo technique. The fourth variation, on the tonic minor, brings with it a moment of reflection before the piano, in another flamboyant outburst, abruptly changes the mood with a fortissimo entrance at the beginning of the fifth variation. The theme is most clearly perceptible in the sixth variation, while the aggressive seventh variation, again on the tonic minor, is built of rhythmic fragments of the theme in true Beethovenian fashion. Only the broad outline of the theme remains in the elegant eighth variation. The final variation again clearly articulates the theme before slipping momentarily into G major and 6/8 meter for a developmental coda that eventually moves back to the tonic and opening meter. Movements : 1.Allegro con brio 2.Adagio 3.Tema. Pria ch'io l'impegno. Allegretto
