Aldo Platteau entered music at an early age through choral singing and the study of the accordion and organ, instruments he later studied at the Conservatoire Royal de Mons. He continued his musical studies there and graduated in singing, early music, harmony, counterpoint, fugue, composition, and composition of applied and interactive music.
In 1998, he joined the Chœur de Chambre de Namur as well as the ensemble Quartz. He performs, both in Belgium and abroad, as a soloist and chorister with prestigious ensembles, participating in several recordings.
In 2000, he was selected by the Fondation Royaumont, which awarded him a scholarship, to participate in the international musical composition seminar led by the English composer Brian Ferneyhough. His works have been performed by the ensembles Musiques Nouvelles, Sturm und Klang, Nouvel Ensemble Moderne of Montreal, as well as by numerous soloists and chamber musicians. His compositions have been premiered in Europe and in the USA (New York). His Concerto for organ, cello, and string orchestra was premiered in 2006 in Cuba (Havana).
His enthusiasm for electro-acoustic music, including the use of modular synthesizers and computers, led him to compose and create the work Lassus, enfant Montois for the large Schijven organ of the Saint-Nicolas Church in Mons, the children’s and youth choirs of La Monnaie, cello, solo singers, and electronic instruments, commissioned by the Fondation Mons 2015.
He also composes music for theater and cinema. Together with Benoît Giaux, he works with the children’s and youth choirs of the Théâtre Royal de la Monnaie. He directs the vocal ensemble Mezza Voce in Mons. Organist in the same city since 1994, he holds, in particular, the historic Schijven organ of Saint-Nicolas Church.
Aldo Platteau has taught composition and ensemble singing at the Académie de musique d’Auderghem, and advanced writing at the Conservatoire Royal de Liège. He currently teaches counterpoint and various musical writing styles, from the Renaissance to the 20th century, at the Conservatoire Royal de Bruxelles, and composition of applied and interactive music at the Conservatoire Royal de Mons (Arts2).
