The Video 1 link shows a piano part pdf file, but download it and you'll find only a full score without any piano part listed in the orchestration. What's with that? The Video 2 link shows a rep list for the Carnegie Hall competition, of which applicants are to choose one or two:
- Schumann: Kinderszenen, Op. 15 Traumerei
- Mozart: Piano Sonata No. 11 in A Major, K. 331, Mvt. III, "Alla Turca" - Allegretto
- Beethoven: Piano Sonata No. 21 In C, Op. 53 "Waldstein" Mvt. 1 Allegro con brio
- Brahms: Intermezzo In A Major, Opus 188, No. 2
Apples and oranges. The Waldstein movement is in a much higher difficulty league than the other pieces, with only the Brahms Intermezzo coming close. I can see Traumerei being the most performed of the four because of its short length and ease of execution. The Mozart is an often overplayed work but can still show sparkle, stylistic integrity, and detail work in fine performances.
Best of luck the pianists in the competition! Email me if you've made a video worth sharing.
