Piano Sonata In A Major

Ludwig Van Beethoven

Introduction

Form to recognize: Rondo Form Structure of form: ABACADA Principal theme “A” (refrain) alternates

with contrasting themes (episodes).

INTRODUCTION OF THEME “A”

Begins in D Major; is in ¾. Tenuto Sempre (always sustained) in treble. Staccato Sempre (always detached) in bass. Has a Perfect Authentic Cadence (PAC), then

shifts to A Major briefly. Shifts back to original key and familiar

rhythmic structure. Notice sudden rise in treble clef, with sudden

fall in bass (such movement can be classified as a tessitura)before the PAC.

“B” SECTION

Immediate change in key to g# minor. However, this is not long. This section becomes harmonically

unstable . Creates tension with:

Pounding eighth note chords (not detached as heard in “A”).

Crescendo into Fortissimo.

RETURN OF “A”

Return of tenuto and staccato sempre. However, after first PAC, treble and

bass “switch” material (providing variation).

Remains similar to original material, leading to a PAC.

“C” SECTION

Entirely new thematic material. Very brief.

RETURN OF “A”

Same rhythmic material, in minor. However, no definite key; harmonically

unstable. Remaining in Staccato and Tenuto Sempre. However, has much ornamentation. Is fortissimo; with marked sforzando (sfz-

giving a strong accent). Range in treble clef is much higher than in

previous restatements of “A”.

“D” SECTION

Sudden new rhythmic and melodic material.

Brief, but significant. Dynamics drop from previous

fortissimo to piano. Has noticeable chromaticism in treble

clef (heard in grouped eighth notes).

FINAL RESTATEMENT OF “A”

Treble clef has much ornamentation. Original rhythmic material is still

evident. Restatement ends on a PAC.

CLOSING THEME Closing theme (coda). Produces relief from tension. Creates sensation of conclusion.
