Born in 1961 in Tunis, Tunisia, Moncef was blind at birth. Flown to Switzerland to receive treatment on his eyes at the age of 2, he was adopted by a Swiss family shortly after. At 6 he began to take piano lessons, strongly encouraged by his adoptive father, a big Jazz fan who would often play records by Louis Armstrong or Fats Waller at the family's house. Blessed with a remarkable auditory memory that allowed him to learn and replicate any piece by ear, Moncef started to develop his own style. In 1987 he obtained a music teacher's degree from the Conservatory in Geneva, where he still teaches Jazz improvisation today.
A professional musician since 1983, Moncef quickly asserted himself as one of Switzerland's leading Jazz artists, thanks in part to the body of work he assembled with his Trio
