the griots belong to specific families and almost form a musical caste within mauritanian society. t’heydinn poems have also been composed by poets not belonging to such families. griots hand down their knowledge from father to son. the father or a qualified relative initiates the young griot into playing musical instruments and later into the arts of music and poetry, culminating in his initiation into the art of the t’heydinn through recitation and mastery of the family’s own heritage. during this period of apprenticeship, the apprentice performer accompanies his father at all events, ceremonies and performances where he can turn practice and acquire new skills on the job. every griot family guards its own t’heydinn repertoire as it distinguishes it from other griot families. a griot in possession of the whole epic is respected by all the other griot families and termed a ‘bearer of the t’heydinn epic’.
