Schubert's Impromptu Op. 90, No. 2, is a masterpiece of harmonic ingenuity, showcasing the composer's exceptional skill in crafting innovative chord progressions and modulations. Through our harmonic analysis, we've uncovered a rich web of relationships between chords, keys, and themes, which underpin the piece's beauty and emotional impact.
The exposition continues with a series of elegant, waltz-like passages, featuring chord progressions that expand on the tonic-dominant relationship. Schubert uses secondary dominants and appoggiaturas to add color and depth to the harmony. For example, in measure 13, a V7/IV chord (E-flat major 7th with a D-flat in the bass) leads to a beautiful IV chord, creating a sense of surprise and contrast. schubert impromptu op 90 no 2 harmonic analysis
Before diving into the harmonic analysis, let's set the stage with some background information. Schubert composed his Op. 90 impromptus in 1827, during a particularly productive period in his life. These pieces were intended for solo piano, and their title, "Impromptu," was chosen by the publisher, rather than Schubert himself. The impromptus are characterized by their poetic, expressive nature and technical challenges, making them a staple of the piano repertoire. Schubert's Impromptu Op
The piece begins with a gentle, lilting melody in A-flat major, accompanied by a soothing arpeggio pattern. The chord progression is straightforward, moving from I (A-flat major) to IV (D-flat major) and then to V (E-flat major). However, Schubert quickly introduces a subtle harmonic nuance: the use of a Neapolitan chord (bII) in measure 5. This chord, E-flat minor, creates a sense of tension, which is later released when the progression resolves to V. Through our harmonic analysis, we've uncovered a rich
The recapitulation returns to the home key of A-flat major, with a restatement of the opening theme. However, Schubert adds a few harmonic twists to keep the listener engaged. For example, in measure 57, a V9 chord (E-flat major 9th) with a sharp 9th (F#) creates a subtle sense of dissonance, which is later resolved.
