Since the beginning of his career, Dr Henri Pompidor has conducted various choirs: children or adult, amateur, university or professional, in France and around the world. Under his direction have been performed much chamber choral music (Italian and French madrigals, French Renaissance “chansons” and madrigals, Romantic and post Romantic “Lieder”) and several major choral works (Wolfgang A. Mozart’s “Requiem” & “Vesperae Solennes de Confessore”, Joseph Haydn’s “Die Schöpfung”, Giacomo Puccini’s Messa di Gloria, , Johannes Brahms’ “Ein Deutsches Requiem”, Maurice Duruflé’s & Gabriel Fauré’s “Requiem”...).

As resident choral conductor for the Thailand Philharmonic Orchestra (T.P.O.), he joined several opera productions (Wolfgang A. Mozart’s “Die Zauberflöte”, Jean-Philippe Rameau’s “Les Indes Galantes”, Claudio Monteverdi’s “Orfeo” or Henry Purcell’s “King Arthur”) and choral performances (Carl Orff’s “Carmina Burana”, Ludwig van Beethoven’s “Ninth Symphony”, Francis Poulenc’s “Gloria”). He has also been invited to perform in many music festivals, especially the French festival “La Fête” in 2012 or more recently in 2013, the concert commemoration of the fifty anniversary of the Élysée Treaty.

Meanwhile, his research on Baroque choral music led him to create in 2009 a new vocal and instrumental ensemble. The Mahidol University Baroque Choir and Orchestra (M.U.B.C.O.) introduced some early repertoire not yet much well-known in the country. Composed of sixty singers and period instrumentalists, the group performed major compositions by Marc-Antoine Charpentier, Michel-Richard Delalande, Jean Gilles, Jean-Philippe Rameau, Jean-Baptiste Lully, Georg Philipp Teleman, Antonio Vivaldi or Johann Sebastian Bach.

Following this initiative, another more independent music group also emerged in 2012 under his leadership: the Thailand Interuniversity Choir and Orchestra (T.I.C.O.). This musical group is still working today to allow cooperation and exchange between music students and faculties, artists from Thai universities and beyond.
