Hilary Hahn herself has been doing '100 days of practice' again recently - she's on day 87 now. Another example I've been enjoying lately is the German pianist Annique Goettler practicing sections of the Moszkowski piano concerto - sometimes she does split screen and also plays a reduction of the orchestral part (on Instagram, also her YouTube "Heart of the Keys" account). She's a pro but has a sense of humor about the ridiculous amount of messy work and frustration it takes to get things polished. See her recent "1 Min, 10 Min, 1 Hour Challenge" for the last movement of the moonlight sonata. This is the kind of thing that in the old days you would only see if you hung around a musician's house. I used to have an older pianist friend who would say "look what I'm working on!" and then crash through some crazy virtuoso piece that months later he would play perfectly. Most kids don't have direct access to musicians at that level, so I really appreciate this trend of practice videos. Plus, seeing behind the curtain makes the music even more interesting.
