This trio follows the classical form: the first movement is a sonata, the second is in ternary form while the third movement is a rondo. The musical texture is polyphonic at a high level of chamber music playing. All three instruments play equal parts both technically and musically. In the first movement the fanfare-like main theme corresponds to the characteristics of the instrument, after which there follows a smooth subsidiary theme. In the recapitulation the melody of the trombone is imitated by the trumpet. The second movement is a lyrical cantilena of broken melody while the third one forms a virtuoso rondo, full of drive. Moderately difficult.
