I think it's very interesting and there's a lot to be gained by working on it (which I'm actually starting to do). The hardest scale in piano is C major probably, or at least one of the hardest ones... just started with Taubman, but C major (and D major) are sounding way better, even with what I would say is not a huge time investment.
any resources or tutorials that were very helpful for you ? would love to get in on that.
There's very good teachers doing zoom lessons these days. And I think Taubman technique is the sort of thing that you'll need a teacher so that the concepts can be applied to how you're playing. Start here https://www.golandskyinstitute.org/faculty-of-the-golandsky-...
Good luck :)
