What’s its purpose? For whom is it intended? From what we know of Gould, he would have been baffled, even horrified, at the idea that a student learning the “Goldberg” Variations would precisely mimic his performance. He was too restless a thinker to consider any recording of his at all definitive. And imitating a pianist as idiosyncratic as Gould may not be a good idea for impressionable young musicians.
This reminds me of when I studied for a Master’s degree in applied linguistics in the 1990s. We did something called conversation analysis, where you would transcribe a conversation, with every “um” and “ah,” every pause, overlap, and so on. It gives you a better understanding of how people interact when speaking.
But for a specific recording of a specific piece of music? It seems like a naval-gazing experiment.
