Marie-Pierre Langlamet was born on September 13, 1967, in Grenoble, France. She first became acquainted and enchanted with the harp through the children’s album Piccolo Saxo. Because she definitely wanted to learn a polyphonic instrument and the piano class was full, she decided to take up the harp. She received her first musical training at the Nice Conservatoire with Elisabeth Fontan-Binoche, later participating in masterclasses given by Jacqueline Borot and Lily Laskine.
At the age of only 15, she attracted international attention when she won the top prize at the Maria Korchinska International Harp Competition, followed by a first prize at the International Harp Competition of the Cité des Arts in Paris one year later. She was only 17 when she was engaged as the principal harpist of the Nice Opera Orchestra. However, a year later, she gave up this position to continue her studies at the prestigious Curtis Institute of Music in Philadelphia.
In 1988, she was appointed assistant principal harpist of the Metropolitan Opera Orchestra in New York (under chief conductor James Levine), where she worked for five years. In 1992, she won first prize at the International Harp Competition in Israel, widely regarded as one of the most important competitions for the instrument.
Since 1993, she has been the principal harpist of the Berlin Philharmonic Orchestra (Berliner Philharmoniker), appointed during the tenure of chief conductor Claudio Abbado.
Alongside her orchestral career, Langlamet performs worldwide as a highly acclaimed soloist and chamber musician. She has performed as a soloist with renowned orchestras such as the Berlin Philharmonic, the Israel Philharmonic Orchestra, and the Orchestre de la Suisse Romande. She has a close collaborative relationship with the American composer Sebastian Currier and premiered his harp concerto "Traces".
In June 2009, she was made a Chevalier dans l’Ordre des Arts et des Lettres by the French Ministry of Culture for her significant contributions to French music. She has been teaching at the Karajan Academy since 1995 and at the Berlin University of the Arts (UdK) since 2010.
