E-flat minor
The final piece in Brahms' Klavierstücke, Op. 118, No. 6, is in E-flat minor. The piece, like many pieces in this key, is dark and funereal, being based on the Dies irae chant. The third movement (Adagio mesto) of Brahms's Horn Trio, op. 40 in E-flat minor, as is the second movement of his Sonata No. 2 for Clarinet and Piano. Schubert ended his Impromptus No. 2, D. 899 in E-flat minor, the parallel key to E-flat major, and so did Brahms in his Rhapsody No. 4, Op. 119. Schumann's Manfred Overture is in E-flat minor, although the string parts are written in three flats with accidentals. Chopin wrote his Etude No.6, Op. 10, his Polonaise No. 2, Op. 26, and his Prelude No. 14, Op. 28 in E-flat minor.
