Accordéon Mélancolique is a Dutch accordion duo consisting of Cherie de Boer (born 10 June 1950 in Jakarta) and Jean-Pierre Guiran (born 27 January 1957 in Vlissingen).

In 1997 they were asked to play during the fiftieth anniversary of the Marshall-plan in Rotterdam, the Netherlands, for, among others, Bill en Hillary Clinton, Dutch crown prince Willem Alexander and former Dutch prime minister Wim Kok.

By consciously using silence next to sound as building stones of their music, even the most simple pieces receive an intense thrill and it gives rhythmic melodies an extra sprakle.

[4]The compositions of Jean-Pierre Guiran are distinguished by the central role of the melody.

The expressiveness is strengthened by timing in various rhythms and by the harmony which receives the role of a second voice.
