Six Preludes and Fugues, Op.
35, is a piano composition by Felix Mendelssohn.
Combining freshly composed preludes with several earlier composed fugues, he composed the entire collection in a plan based on alternating minor and major keys (E minor, D major, B minor, A-flat major, F minor, B-flat major).
This composition is influenced by Well-Tempered Clavier by Johann Sebastian Bach.
