There has never been any other composer who has mastered the fugue to the level of J. S. Bach.
His was a mind that excelled in complexity and subtlety. It seems like the idea of the fugue was invented just for him.
The first two fugues were originally for organ, the third for harpsichord. In arranging them for three separate voices it is considerably easier to identify the interaction written into the counterpoint.
The first player has a slightly more difficult part but, as is the nature of fugal writing, all the parts are melodically important virtually all the time. This is Bach in his element. 13 mins. M
