It is very important to practice those unusual accents correctly. Play staccato with light feelings like hopping. Allegro - fast, cheerful. The left hand plays melody and the right hand accompanies in mm.9-16. Try to play lightly like bird flying with the attention to dynamics.
Triplets are very tiny and vertiginous, but practice to play evenly with clear articulation.
At the codetta , the tune starts falling away, expressing resignation. Remember these points throughout the piece, try to make melody sung, and pay attention to balance of the sound. This piece is a waltz. Make clear distinction of legato and staccato . The right hand plays accompaniments and the left hand plays the melody in the beginning part and ending part.
