The return of the hobbit hands XDDD
in the old days, people (Europeans) were smaller in average. These aren't the olden days. I still need hard proof that theres a large pool of ADULT females that are incapable of reaching octaves, and just how many of them are serious pianists...
Because honestly, there's no point in making another "standard" when the market isn't there.
And now OP's jealous of people who can plays 10ths comfortably? Then again I've seen 10ths here and there, especially in popular accessible works. Chopin op. 63 no. 3 mazurka, quite a few stretches there near the end. And I can play them comfortably~
Be jealous hobbits!
