Yeah, I usually like Neely’s vids, but that one came across poorly to me, almost like a thinly veiled brag of his knowledge of non-western scale intervals and tempos. Meh, not my favorite Neely vid.
That said, this tests nothing about potential aptitude at playing music. Though that is much more about putting in the work than it is about natural potential, at least in non-extreme cases. So he got that right.
