Beethoven Piano Sonata No. 14 III Presto agitato

The stormy final movement (C♯ minor), in sonata form, is the weightiest of the three, reflecting an experiment of Beethoven's (also carried out in the companion sonata Opus 27, No. 1 and later on in Opus 101), namely, placement of the most important movement of the sonata last. The writing has many fast arpeggios/broken chords, strongly accented notes, and fast alberti bass sequences that fall both into the right and left hands at various times. An effective performance of this movement demands lively and skillful playing, great stamina, and is significantly more demanding technically than the 1st and 2nd movements.

Of the final movement, Charles Rosen has written "it is the most unbridled in its representation of emotion. Even today, two hundred years later, its ferocity is astonishing".

Beethoven's heavy use of sforzando notes, together with just a few strategically located fortissimo passages, creates the sense of a very powerful sound in spite of the predominance of piano markings throughout.
