Claude Debussy wrote "Syrinx (La Flute De Pan)" based on Pan's sadness over losing his love. This piece was the first unaccompanied flute solo of the 20th century, and remains a very popular addition to the modern flutist's repertoire. In classical mythology, Syrinx (Greek Συριγξ) was a nymph. As she was chased by the Greek god, Pan, she ran to a river's edge and asked for assistance from the river nymphs. In answer, she was transformed into hollow water reeds that made a haunting sound when the wind blew across them. Pan cut the reeds to fashion the first set of pan pipes, which were thenceforth known as syrinx.
