Beethoven's Fifth Take note of any unusual treatment of Sonata Allegro form that is identified in this humorous video: The theme is not really a theme, but a motif that is used to create the theme. The transition to the second theme is very short, as the motive has already been developed to a new key. The development works with the four note motif rather than any proper theme. The four notes are developed down to two notes, and finally one note. The recapitulation contains a cadenza for the oboe. The Coda is usually a very short cadence that puts the finishing touch on the movement. Here, the coda is extended, containing a new theme, and a new development.
