Résumé

Cette etude a examine la perception de deux instruments joues en meme temps, les deux instruments etant choisis d’entre le clarinet, le trombone, et le harp. Les stimuli etait contenus dans deux portions fixes (300 ms) des timbres produits par les instruments choisi. Quarante paires etaient construites pour quatre types des conditions: trois conditions experimentales de timbre instrumental, et une condition controle de pure ton correspondant a la frequance fondamentale de ce timbre. Une trentaine d’etudiants, avec et sans formation musicale, ont ecoute a un melange de quatre cents stimuli randomises. Les participants devaient identifier si le stimulus presente etait compose d’un ou de deux instruments de musique. Nous avons trouves que les participants avec une formation musicales etaient en general plus doues. Ceci peut constituer une indication que la formation musicale ameliore l’abilite de reconnaitre des timbres. Une discussion des differences dans le groupe experimental est presente.
