Burgmüller's most famous work, the 25 Progressive Pieces, are short compositions with descriptive titles. Easier than his Opp. 105 and 109, each selection exposes students to a different technical challenge with the main emphasis on the phrasing, articulation, and dynamics often found in Romantic piano music. The collection includes 'Arabesque' and 'Ballade,' both popular with many early-intermediate pianists.
