Au bord d'une source (Beside a Spring) is a virtuoso piano showpiece 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'une 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; this lengthened the piece by about 30 seconds. The coda was written in 1863.
