Au bord d'une source ("Beside a Spring") is a piano piece by Franz Liszt; it is the 4th piece of the first suite of Années de Pèlerinage ("Years of Pilgrimage").
There are three separate versions of Au bord d'une source. The first version appears in Liszt's set Album d'un voyageur (1834–1838), and the second in the first suite of Liszt's Années de pèlerinage (1836–1855). The last version is almost identical to the second, except for the final nine bars, which were added by Liszt as a coda for his Italian piano student Giovanni Sgambati, who was also a composer;[1] this lengthened the piece by about 30 seconds. The coda was written in 1863.[2]
The second version of Au bord d'une source is often regarded as the most popular. In the first version the technical difficulties are considerably higher to the pianist, whilst the last version adds a flashy coda.[3][4]
