I spent about 3 weeks working on this one (at the time of this video), along with other pieces. Measures 45-51 were the most challenging, and I don’t think I have them sounding like they should. I also had trouble with pedaling, it’s still not perfect. Other things that have me hard time: Ornaments in measures 26, 42 and 58. 16th notes in measures 21 and 53. And my kid managed to blow a whistle right at the start :-D
