This piece by Alfred Jaëll reflects the mid-Romantic penchant for tone painting, specifically the sound of water. It is marked by its rich, undulating textures and demands a sensitive approach to pedaling.
The biggest challenge is achieving a seamless blend between the rolling arpeggios and the highlighted melodic notes.
