A graduate from the Royal Conservatory of Liège in Belgium (1st prize organ, 1st prize harmony, 1st prize history of music, 1st prize musical analysis); Sébastien Letocart is a self-taught composer, who has built his musical equally by studying ancient music (i.e. Josquin Desprez, William Byrd, Tomas Luis Vitoria, Roland de Lassus, Jan Pieterszoon Sweelinck, Claudio Monteverdi, Dietrich Buxtehude, Johann Sebastian Bach), practicing it (organ, harpsichord and singing) as well as analyzing the great scores of the Classical Symphony (Haydn, Mozart), the Romantic (Beethoven, Schumann, Brahms, Dvořák, Bruckner), the Post-romantic (Debussy, Roussel, R.Strauss, Mahler, Sibelius, Nielsen) and the symphonic repertoire of the first half of the 20th century (Bartók, Hindemith, Stravinsky, Shostakovich, Bax, Vaughan Williams, Holst, Walton, Honegger, Martinu, Varèse). He is also highly interested in the music of the last sixty years, his preferences are going from György Ligeti, Iannis Xenakis or Esa-Pekka Salonen to Einar Englund, Aulis Sallinen, Emil Tabakov, Kalevi Aho, Vagn Holmboe, John Adams, Sir Malcolm Arnold or Sir Andrzej Panufnik. He is also greatly attracted by chamber music, especially by the refined writing that the string quartet demands and by Béla Bartók's six String Quartets which are the nec plus ultra of the genre.
