Julius E. Müller's Budding Leaves is a character piece that mimics the delicate rustling of spring foliage through light, running figures. It is a pedagogical work of the mid-Romantic era that emphasizes light touch and finger dexterity.
Focus on the evenness of the scale passages to avoid unevenness in the sixteenth-note figures.
Comparable difficulty and character — good candidates for what to learn next.
