How does Bach's original Fugue in G Minor differ from Stokowski's arrangement?

Bach's original Fugue in G Minor was written specifically for the organ, which is a solo instrument capable of producing a rich and complex sound. In contrast, Stokowski's arrangement reimagines this piece for a larger ensemble, allowing for a broader orchestral texture and a variety of instrumental colors. The transformation from a singular organ sound to a full orchestra changes the character and adds depth to the music, showcasing how arrangements can reinterpret works for different contexts and audiences.

This understanding highlights the significance of instrumentation in music and how it influences the listening experience. While the other options may describe various arrangements and instrumentations, they do not accurately capture this fundamental difference in the medium used for each version. Therefore, the answer accurately reflects the most crucial distinction between Bach's original composition and Stokowski's adaptation.
