What does The Well-Tempered Clavier sound like in actual well temperament?

This episode features Glenn Gould's 1963 recording of Johann Sebastien Bach's Prelude No. 1 in C Major from The Well-Tempered Clavier Book I, BWV 846 (1722). I also tempo-mapped Gould's performances of other WTC preludes and used them for the tempos of the MIDI versions of the various movements. A small correction: I say in the episode that five-limit just intonation is the basis for Western European tuning systems. This is only true from the Renaissance onwards. Medieval Europe used Pythagorean (three-limit) tuning. Also, just intonation was probably more of a theoretical ideal than a practical tuning method. Also, at one point I mistakenly refer to Bach’s F-sharp major prelude as the F-sharp minor prelude. I did the alternative tunings using MTS-ESP (https://oddsound.com/mtsespsuite.php) . I used the following tuning ratios for the just intonation parts: C - 1/1 C# - 16/15 D - 9/8 Eb - 6/5 E - 5/4 F - 4/3 F# - 45/32 G - 3/2 Ab - 8/5 A - 5/3 Bb - 9/5 B - 15/8 I also used quarter-comma meantone, Andreas Werckmeister's temperament III from 1681, and Johann Kirnberger's well temperament as described in a letter to Johann Nikolaus Forkel in 1779. In actual practice, Europeans tended to center their tuning around D rather than C. I stick to C for ease of explanation, not historical accuracy. Here are some real humans performing music in historical European tuning systems: Alice Borciani, Eva Saladin, Brigitte Gasser and Johannes Keller perform a Sabbatini motet in quarter-comma meantone:    • G. Sabbatini: Derelinquat impius viam suam   Daniel Adam Maltz demonstrates Kirnberger:    • Wolfgang Amadé Mozart: Sonata in F Major, ...  ) Carl Radford demonstrates Young’s temperament:    • Classical vs Modern Tunings - C# Major Pre...   John Moraitis demonstrates quarter-comma meantone, Rameau and Kirnberger:    • Comparison between meantone and Rameau tem...   Alice M.

You can hear Dr Charles Tebbs demonstrating Lehman’s tuning (   • Bach: demonstration of piano in Lehman's '...  ) , and if you have a longer attention span than I do, you can watch Lehman tune a harpsichord (   • Tuning a harpsichord in Bach's temperament...  ) .
