Gould revered J.S. Bach, stating that the Baroque composer was "first and last an architect, a constructor of sound, and what makes him so inestimably valuable to us is that he was beyond a doubt the greatest architect of sound who ever lived". He recorded most of Bach's other keyboard works, including both books of "The Well-Tempered Clavier" and the Partitas, French Suites, English Suites, Inventions and Sinfonias, keyboard concertos, and a number of toccatas (which interested him least, being less polyphonic). For his only recording at the organ, he recorded about half of "The Art of Fugue", which was also released posthumously on piano.
