Au Bord d’une Source (“Beside a Spring”) is the 4th piece of the first suite of Années de Pèlerinage (“Years of Pilgrimage”) which was composed between 1835 and 1838 and published in 1842.

The music begins with a gentle, flowing melody that represents the babbling of a spring. Liszt uses arpeggios and delicate trills to create a sense of water cascading over rocks. As the piece progresses, the melody becomes more complex and the harmonies richer, perhaps reflecting the increasing depth of the spring as it flows. He uses dynamic contrast to convey the ebb and flow of the water, as well as sudden bursts of energy that suggest the rush of water over rapids.
