And one final thing. I learned that I can also play Rachmaninov as modern for this specific examination. So i am really tempted to play Moment Musicaux No.4, which I really love and it doesn't seem too difficult. What do u think of that?
How about some Joplin rags composed 1900-1915? They typically run 3-5 min.Bethena - sub-titled a concert waltzThe Entertainer - popular, but not frequently played as Joplin intended.The Cascades - has some difficult partsGladiolus Rag - interesting effects with pedaling.Fig Leaf Rag - a very modern sounding rag.
As for Sorabji, I haven't listened to the 1920 toccata, but come on, it's Sorabji. Every piece from him that I have listened to seems too comlex. Anyway...
