This orchestral interpretation unites the Preludium and Fugue from Johann Sebastian Bach’s The Well-Tempered Clavier, Book I, originally composed for keyboard in 1722. The work exemplifies Bach’s mastery of tonal architecture, where the radiant Preludium’s harmonic breadth seamlessly contrasts with the Fugue’s intricate contrapuntal depth. In Bohdan Tykhanov’s orchestral arrangement, both parts acquire a new sonic dimension. The Preludium’s luminous elegance and rhythmic poise are expanded through orchestral color, while the Fugue’s intellectual rigor is reimagined in a vivid polyphonic dialogue between instrumental sections. The result preserves Bach’s timeless spirit while revealing the latent symphonic potential within his keyboard writing.
