"Allegro vivace" is besides Cossack Dance the most difficult piece of the set. It features fast parallel blocked thirds, both in staccato and legato. Further difficulties include some surprising rhythmic shifts, quick pedal changes, and speedy LH broken 5ths in staccato articulation. If the young pianist masters this composition, he/she will have a great recital/competition piece!
