Jardins Sous la Pluie from Debussy's Estampes Suite.
One of the important things that I learned while playing this piece with my piano teachers is bringing out the melody. When I hear various recordings, often the notes are played all at the same volume, so the melody isn't clear. I always like to think of orchestration when I'm playing pieces on the piano. That helps me learn to highlight the melody. I also love the various harmonies and how it transitions from the rain into the sun at the end of the piece.
