This bold gesture is answered by quieter, connected phrases, and the contrast continues throughout the movement. Running passages, broad singing melodies, and closely interwoven voices expand the material into a large structure. The main ideas return with altered accompaniments before an extended closing section.Opening and transition: The opening chords are separated by rests and shaped by dotted rhythms and sharp accents. A soft reply introduces ties and a more continuous melodic line. The upper part soon develops moving eighth notes around a held or slower voice, while the bass descends beneath it. Strong upper chords then alternate with shorter replies over active lower chords. Wide leaps, changes of register, and brief hand crossings lead into running figures shared between the hands.Contrasting melodic material: A passage marked Tranquillo brings a lower melody beneath upper rests and chord responses. The upper line later moves through chromatic phrases above long bass harmonies. Inner eighth notes keep moving beneath sustained melodic tones. After a livelier exchange of chords and runs, a cantabile melody appears in longer upper notes over a steady lower pattern. An extended trill continues beneath the upper melody while the left hand moves through broken figures. Fuller chords and wide eighth-note motion lead to the exposition’s alternate endings and repeat.Middle section: Quiet lower running notes accompany short upper chords before an imitative passage begins. Small figures pass between voices, overlap, and gradually fill the texture. Accents and larger chords increase the weight of the music. The hands sometimes cross into the same register, and long notes continue sounding against more active parts. A very strong arrival gives way to another soft cantabile passage. Chromatic motion and renewed exchanges then build toward the return of the opening.Return and extended ending: The principal chordal gesture returns over moving left-hand octaves. Its quieter reply is expanded through altered inner voices and harmonies. Familiar running passages and the singing material reappear in changed settings. Another long trill supports an upper melody, followed by strong octave and chord patterns in both hands. A quieter passage introduces overlapping trills before the final page turns to softer runs and short chord responses. Low left-hand eighth notes continue beneath fragments of the main idea as the sound diminishes. A sudden fortissimo chord provides the last strong gesture before the sustained final harmony.Interesting fact: The title page prints the German name “Grosse Sonate für das Hammer-Klavier,” the source of this sonata’s familiar Hammerklavier name.How to earn points for this piece:Download or purchase the sheet music.Practice the piece carefully.
