Complex Numbers » difficult + musical pieces
By most any standards the following are among the most difficult to play of all piano pieces. They require huge finger spans, tricky fingering, and unmatched finger speed.
Piano Concerto No. 3 in D minor, Op. 30 (a.k.a. Rach 3) by Sergei Rachmaninoff
Piano Concerto No. 2 in G minor, Op 16 by Sergei Prokofiev
Transcendental Etudes, No. 5 in B-flat, "Feux follets" by Franz Liszt
Études, No. 1 in C major, Op 10 by Frédéric Chopin
For a sure smile read the lyrics and then listen to “Franz Liszt The Famous Pianist” set to the tune of Liszt’s Hungarian Rhapsody No. 2. All the songs available on the Beethoven's Wig CDs are great! A real hoot!
