The loud calls of a monogamous, territorial ape, the lar gibbon (Hylobates lar) are described and illustrated with somograms. An overview of its repertoire of loud calls, their organization, contexts and functions is attempted. The description is based on a 2 yr study of a wild population in Khao Yai National Park, Thailand. Seven classes of call bout are distinguished: male solo, male dispute calls, female solo, normal duet by bonded pair, ooaa duet (similar to normal duet, but more infectious to other groups), disturbed calls and contact calls. The organization of the normal duet is described in detail, showing the coordination of the sexes, the development of the male part through the call bout and the presence of individual and pair differences. Discussion considers the possible functions of duets, of male solos and of disturbed calls given in reaction to man.
