Alain Louvier (born 13 September 1945) is a French composer of contemporary classical music.
Born in Paris, Louvier studied from 1953 to 1967 at the Boulogne-Billancourt Conservatory [fr] headed by Marcel Landowski, then from 1967 to 1970 at the Conservatoire de Paris with Henriette Puig-Roget, Olivier Messiaen, Tony Aubin, Robert Veyron-Lacroix, Norbert Dufourcq and Manuel Rosenthal.
From 2009 until 2013, he was again director of the Boulogne-Billancourt Conservatory Louvier has composed pieces for piano, harpsichord, chamber music and orchestra.
He is particularly known for his invention of a new piano technique (also used on organ and harpsichord) centered around the "aggressors": the 10 fingers, 2 palms, 2 fists and 2 forearms, treated individually.
He forged a precise gestural vocabulary, and an adapted graphic syntax, involving these different elements.
